Thanks in advance for any input! Alex Dorades Reputable. Mar 28, 1 4, Balance CPU and cache ratio until you get max temp 80c. Or leave cache as it is and rise CPU and if there is room some temperatures rise cache to reach the max temp. Alex Dorades :. Cache frequency can't be more than the CPU frequency. If you set cache more than cpu pc will crash or don't start at all. I know what you mean. I think its a voltage one.
Try to rise voltage more. If you rise voltage it have to working. Maybe you don't reached the point of voltage that the system needed to work stable.

Page 1 of 2 1 2 Last Jump to page: Results 1 to 10 of Maximum CPU Cache Ratio made a huge difference I was seeing bad scores for a DDR4 memory and at the xmp and i was trying to find why I couldn't find a solution as long as i searched, that doesn't mean i search everything.
So i changed the max cpu ratio to match the multi of the cpu so the NB clock matches the core clock. The results are surprising especially the write. Minimum 24 and Maximum 24 set by default. Minimum 24 and Maximum 37 set with volt on auto A full set of tests on Aida 64 Anyone else that played with cache ratio and if some results. Hello Yes, cache speed has an impact om memory performance at higher memory speeds.
However, there are few applications that will take advantage of this increased bandwidth. It is normally better to prioritize stability and cache voltage before maximum speed. Arne Saknussemm how much volts for cache? That's 1.
Yea i guess so, asking around some friends with haswells haven't heard anyone getting to that clocks on cache. I just test now how low the volts can be stable.
Tnx for the reply.The park game trailer
I'm running 1. Have it set to auto, and if I drop it down manually to match vcore, the system won't boot. Last edited by RIacobo; at PM.
How to Overclock an Intel CPU: Get the Most MHz from Your Processor
Reason: Added exact speed numbers. I would not run cache voltage that highA place to share information, help those who are new to overclocking and brag about your latest sucessful overclock!
CPU Cache Ratio? The only time I wouldn't leave it at stock is on a heavy overclock. Perceived wisdom is you want it within of your CPU multiplier. So at 4. Truth be told there isn't a lot of solid evidence out there that it makes a huge amount of difference but it's one of those rules I've always tried to follow.Ksb pumps houston
Oddly on my k, when I run at 5ghz, the Cache ratio is also happy to run at 5ghz, I've never had a chip where I can match the cache to my max core multiplier and I did see a fair bump of around 15 points in Cinebench between that and 42x, that was entirely repeatable.
Once you drop that down to 46x or so the difference becomes negligible and within margin of error really. Hey quick question. However, if I do not set the Min to x50, it only boosts to x I would like to keep the min Auto to allow it to downclock in idle states. Is there any way to have it reach 50 while still being able to downclock? Edit: just figured it out after posting. Was the option "Ring Down Bin" in my Asus bios. I disabled it and now am getting the full x8-x50 range.
Much like the core clock itself, I see little to no point in letting it downclock to be honest. Glad you got it working how you want though. It's best to leave cache at stock. Overclocking cache doesn't really do too much for performance and it can destabilise your overclock. The best ratio isbut most chips don't let you push it as high as the CPU multi unless you bump the voltage on it and that adds more heat.Microbiology flow chart
Recommended if cant keep is lower than the CPU multi. Mine will let me run up to 4. Is over 4. Those chips were good overclockersit's not uncommon to hit 4.I say minimised as they still happened once in a while and what seems to have cured them is disabling the Intel Turbo Booster. I have been using the Intel Extreme Tuning software but I could not find out how to kill the Booster.
I have tried altering it and the Benchmarking in the Extreme Tuning software does not give a reliable pointer to whether 39 or 42 are better. Can someone explain what this Cache is supposed to do and which is likely to be the right setting? In another thread you said you are not overclocking but your CPU ratio indicates otherwise.
CPU OC vs Cache Ratio OC
At 42 multiplier and the bus at mhz you are running at 4. That is overclocking. For stability usually people dial Cache ration to about mhz less than CPU speed.
The Turbo setting doesn't play any role at this point because you are already over the Turbo speed. If you set CPU ratio to 35 then Turbo speed will increase to 39 when needed and more likely only on one core. As of right now you are running at 4.
If you are still not running stable and your cooler is good now more likely your voltage is too low. Bump it up. For example if you are at 1. This is just an example because I am not sure what is standard voltage is.
And one more thing. CPU running cool is not everything to make system stable. Your motherboard has other components that could run hot and you wouldn't even know it. And don't assume that motherboard manufacturer took care of it. That is why case ventilation is also very important. Even sometimes directing fan on top of the CPU cooler such a way that it blows some air on other components could make a difference.
Photography Director for Whedonopolis. The above shows what I believe is what you need to know about my CPU. Above screen above looks good but again I am not really sure about the voltage.A place to share information, help those who are new to overclocking and brag about your latest sucessful overclock! CPU Cache ratio? Cache clock speeds barely affects performance at all, leaving it at 41 is fine, recommended even. I've played around with it a bit on mine I can take it up to without much issue.
Anything past that and it makes it much harder to stabilize an OC. I keep it at 41, and maximize core speed. Core is king. Cache speed offers some performance, but you'll gain more from a higher stable core speed. In a perfect OC where everything works as intended you would have a one to one ratio between cache and core. Both 47 in your case. However, increasing cache takes voltage and power, so increasing your cache may cause instabilities if you do not adjust the voltages.
You should always use your own judgement and realise that the only person responsible for any damage caused by overclocking is you. This subreddit is for links, discussions and questions about overclocking and underclocking. More general hardware-related links, discussions and questions should be posted elsewhere, even if they happen to relate to a system that happens to be overclocked.Core i7-10700K Overclocked to 5.3GHz With MPG Z490 Carbon EK X - SkatterBencher #11

When it comes to developments in processing, most people tend to look at things like frequency and transistors, but an important, and often overlooked, aspect is CPU cache. So what exactly is CPU cache? Read on to find out. Simply, cache is just a really fast type of memory. A computer has multiple types of memory. The first is primary storage, which could be a hard disk or an SSD and which stores all the heavy data like your operating system and programs. Next is the RAM, much faster than your primary storage; and lastly you have cache, which comprises of the even faster memory units that the CPU holds within itself.
Cache is similar to the main memory or RAM in that when you shut your computer off, it loses its memory, and then begins collecting information from scratch the next time you fire your computer up.
Cache can also be confused with virtual memory, but these are two different things. Virtual memory is what allows your computer to run multiple programs at the same time without losing data, whereas cache moves the inactive data within your operating system from the RAM to disk storage. Computer memory works in a hierarchal system, and knowing this can help you understand how cache itself works.
Remember that this hierarchy is based on the speed, and cache, being the fastest, is thus at the top of this hierarchy. As already mentioned, it is also a part of the CPU itself; which makes it closest to where the central processing itself happens.
CPU Cache: Everything You Need to Know
To break it down, whenever you run a program, a set of instructions makes its way from the primary storage to the CPU. Modern CPUs can process an enormous number of instructions like this per second, which means they need ultra-fast memory at the same time. This is where cache plays its part. The cache carries this data back and forth inside the CPU as it processes the instructions being given to it. A further hierarchy exists within the cache itself; this is described next.
CPU cache is further divided into three levels based on the size and the speed of the cache. These levels are called L1, L2, and L3; with L1 being at the top of the hierarchy. It also holds the data that the CPU is most likely to use when completing a task, so it is also the one that is most used. L1 cache used to go up to about kB, but there are much more powerful CPUs out there now which can take it up to 1 MB.
L1 cache comprises both instruction cache, which provides the information regarding the task that the CPU is about to perform; and data cache, which holds the necessary data on which the CPU is performing that task.
Next, we have L2 or Level 2 cache, which is slower than L1 but much larger. L2 holds the data that the CPU will need next once it is done using L1 data. In modern computers, the CPU contains L1 and L2 caches within its cores, and each core gets its cache. Finally, L3 or Level 3 cache is the slowest form of cache, but also the largest ones.
Its size ranges from 4 MB to 50 MB. Most CPUs have a separate dedicated space for L3 cache. L3 serves as a backup for L1 and L2 cache, and it also helps boost the performance of its predeceasing levels of cache. Every time the CPU looks for data with which to run a program and so on, it tries to find it in the L1 cache first. If your CPU is successful in finding it, this is known as a cache hit. If the CPU cannot find the needed data in L1, it proceeds to look for it in the remaining levels.
This is called a cache miss. Cache ratio is thus a ratio of cache hits to misses and it measures how effective a cache is at fulfilling requests for content. Cache voltage is important when it comes to overclocking a CPU. There are three different types.Overclocking Intel processors used to be a very complicated process.
Nowadays, motherboard manufacturers have created automatic overclocking software and one-button predefined presets in the BIOS. While both alternatives produce satisfactory Intel overclocks, they are not perfect and there is always room to improve. More often than not, you could achieve better results by taking the time to manually overclock your Intel CPU instead of having a piece of software do it for you.
Furthermore, you also get to learn more about your system, and, as they say, knowledge is power. Whenever you run an Intel processor outside of the manufacturer's specifications, you're voiding the warranty. In addition, there's always a possibility of premature failure if you overclock an Intel CPU incorrectly.
Nevertheless, if you approach overclocking an Intel CPU responsibly, you can squeeze every single megahertz out of the processor. Intel designates the overclockable models with the "K" suffix. And, of course, there are the F-series graphics-less counterparts to the aforementioned SKUs and the special-edition Core iKS that also support overclocking.
Intel chipsets with the "Z" suffix are the only ones that enable overclocking. If you're not sure of the quality of the VRM on your motherboard, reviews are a great place to start. Never overclock on a stock cooler. It's a blessing that Intel stopped including stock coolers with the brand's K-series chips so users don't fall to the temptation to overclock their chips with these pieces of copper.
Both aftermarket air and liquid coolers are good at what they do. It just comes down to budget, clearance space inside your case and personal preference. It's important to evaluate your power supply's capacity to see whether it has the necessary headroom to accommodate the increased power draw. An underpowered power supply might lead to unwanted system shutdowns and restarts or, in a worst case scenario, the power supply dies and takes a few of your components with it. For context, our tests show that the Core iK can pull up to W of power at stock settings.
When overclocked to 5 GHz, the power consumption increased by 50W. There are online power supply calculators that estimate the power draw for you or you can get a Kill-A-Watt meter to measure it yourself. The Performance Tuning Protection Plan basically covers processor failures due to overclocking.
We think it's a reasonable price to pay to protect your hard-earned investment. No two motherboards are the same. Brands tend to overcomplicate things for the end user by using different terminologies for the same thing. Most brands include a short description for each option inside the BIOS. You should have no problem finding the equivalent term for your motherboard.
There are a plethora of settings and voltages that you can play with that directly and indirectly affect your processor. For the scope of this article, we'll only be focusing on basic settings to get your overclock up and running. Enter the BIOS. Our tutorial on accessing the BIOS explains how, but for most desktop PCs, hitting the Del key on your keyboard as soon as you see the motherboard logo pop up on your monitor works.
Enable XMP to automatically setup your memory modules to run at their advertised speed. If you're running faster memory, make sure your system is stable before overclocking the processor. You want to avoid guessing if future system instability is caused by the memory overclock or the processor overclock.
Set the CPU multiplier to your desired overclock. There are two different approaches to this step. You can gradually increase your processor's frequency using MHz increments until you've hit the wall, or you can set a desired frequency and work your way up or down from there. Intel markets the single-core boost clock speed for its processors.
