I am getting upper 50's right now at 4.6 1.32 (I think) volts. I will post a ss when the test completes.
I can't get real high clocks or temps, but I think this suffices:
Did you pass?
Impressive performance. Very nice. What are you using for cooling? Not familiar with that cpu. I looked up X5620 on Intel and couldn't find any info. Are you running 2 of them? Any photos?
At their stock speed, 1600mhz. Dont see much point in ram overclocking.
It's being misreported, it's actually 2x L5640 CPUs. I'm using H100s to cool them, but since the CPUs are low voltage....
I'm hitting 77-80C with my 2500k @ 4.2 on 1.272v w/ 1.6v PLL (and PLL overvoltage disabled).
I liked this GeminII S on my old AM3 stuff, but it doesn't have anything on an OC'd 2500k.
What about your ram timings? RAM linked to CPU? Very nice score.
I don't understand the performance numbers from IntelBurnTest as they are all over the place for the same CPU. For example in this thread some people have 50s and 60s for their Gflops with a 2500k, and some have over 100 Gflops with the same 2500k CPU.
IBT 2.53 requires windows 7 SP1 to support AVX processing. http://software.intel.com/en-us/avx/ AVX has alot to do with performance on applications that support AVX. Part of the Sandy Bridge processing performance upgrades over prior architectures.
Are you suggesting some people are running Intel Burn Test on their 2500K without Windows 7 SP1 installed? Otherwise I don't understand how this information would be relevant to my original question?
Also why do 2500K's outperform 2600K's in this test in the context of GFlops? Is it calculating GFlops divided by number of perceived CPU cores in some manner, and thus any CPU with HT will have a lower score in that regard?
Yes. That is very possible. The 2nd Generation SB benefit from W7 SP1 because it enables AVX performance increase.
Not sure. Could be that Hyper threading slows down the over all processing effectiveness.
Testing on "Standard" seems like a bit of a waste. That amounts to 75 to 90 seconds of testing and is barely enough to start saturating components and increasing case temps.
For testing stability yes, but for temperature it makes little difference.
i5-2500k @ 4.7ghz, 1.335v. CM Hyper 212+ Evo.
Ambient Temp. at ~22.8C. Vcore set in BIOS to 1.425v with LLC @ 75%, ASUS P8P67 Deluxe.
Very nice results. I wish my MSI Z68 GD65 G3 had LLC settings.
What do you have PLL set at? In/out voltage?
I think everyone should use Maximum. Tthen 25 times anx max threads. Just so we get some consitency.
These are my results with my old Cogage TRUE Spirit using a Scythe Slipstream 1900RPM fan. Ambient temperatures were around 18.8C. It was a great cooler but it just wasn't up to the task anymore.
