Nope but I've done that now and been getting 57 Gflops, still pretty low

Nah, sounds better. I mean, I get that @ 4.7ghz, but I'm running 1866 8-9-8. I assume your ram is much slower.

Ahhh yes that could be it I am running them at stock a the moment

linX 20 runs. no AVX. pic with volts under load ( second linX runing there for 1 min, to push the volts again).
Had a bsod on idle with my previous settings. lowering PLL seemed to solve the problem. PLL 1.8 -> pass linX 10 runs, bsod on idle in 30 min. PLL 1.74 -> no bsod idle, no bsod in games ( tested overnight and then during the morning before lectures). Bsod during 6th run of LinX. Bumped PLL to 1.76 -> passed 20 runs of linX, then waited for an hour playing MK (

lol), then took the screenshot, so far no bsod. I'll check back if I do get an idle bsod. But it seems that lowering PLL does help getting stable.

Do I own a GOLDEN i5 2500K? Seems like it

My new i5 2500K purchased from Newegg is running flawlessly at 5Ghz core on air. Ran Dual Super-pi (1.5rev) five times in a row with no errors. Highest temps per core was 60C 59C 59C 59C. Played Crysis2 for 3 hours solid with no issues.

My Rig:
Thermaltake V9 Case with 2 drive docks.
ASRock P67 Extreme 6
Intel i5 2500K @ 5.0Ghz - 1.42V Core in BIOS - 1.40 indicated by CPUZ
COOLER MASTER Hyper N 520 CPU cooler with Arctic Silver 5
Gskill Ripjaws 1600Mhz - 2X4GB - 7-8-7-20 timings
OCZ Vertex3 240GB on SATA3 - ATTO Benchmark - 560Mbps Read, 527Mbps Write
Seagate 320GB sata2 hard-drive for backup
PowerColor PCS+ AX6970 2GBD5
Seasonic X650 Gold PSU
Liteon Blueray and DVD - Both read and write

Run linX or prime95 and let us know if it is still golden

Screenies too, please.

Here is a Screen Shot as attachment - i5 2500K@5Ghz

Linx and CPUz
First time I have attached, so I hope its there. If not I will try again.

LagunaX · Apr 23, 2011

That's nice so far and really fast times - is it the Vertex3?
However, you are only testing less that 1 gb out of your 8gb of ram (click on all ram in linX)
Your gigagflops seem unusually low for a 2500k - maybe due to not using enough ram.
Seems like a great chip though...is PLL overvoltage on or off?

LagunaX · Apr 23, 2011

BTW this the is best i5-2500k I've ever seen:

PLL Overvoltage is enabled. Yes do have a Vertex3 240GB. Fast
havent tried to push the core to a lower voltage yet

Alex-Ro's 2500K sample was from a batch that seems to have produced some outstanding clockers... L041C124.

Here is another that I believe is also from that batch...

Seems I have to turn off OverSpeed Protection to get past x39 multi :laugh:

Will test out 4.0GHz right now lol

EDIT: Nah, nevermind that. Even if I pass the stability tests right now that doesn't mean I can keep it at 4.0GHz, considering ambient temps when the aircon isn't turned on :laugh:

Frizz · Apr 27, 2011

5Ghz stable, 1.435 in BIOS and 1.44vcore in windows I think I have quite the average chip

My temps were alot better than I expected, I noticed the H50 performs better at higher temps.

can you get the bclk to 100.0?

Frizz · Apr 27, 2011

cadaveca said:

no idea how other than raising bclk settings, would it provide much difference other than round up the numbers? It is currently set to 100.00 as default in BIOS.

Yes, bascially every CPU i've used, 13 so far, behaved fairly different with 100.0+ BCLK. The biggest, most noticible impact immediately is loss of the top-most multi that will boot into windows, as well as a few other things that varied between cpus, like how memory scaled, etc.

I have set 100.3 to get it to 100.1.

My Biostar board did the same as Random's when setting the the BCLK to 100, before updating to a newer bios. It's interesting that the top end was affected by such a small BCLK adjustment.

Paulieg said:

Yes, in the CPU-Z shot I put just above here, 47 is max until 100blck, then 46 is max, and @ 103 this changes down to 45.

All the chips behaved relatively the same, except for very small differences in bclk where the multis were lost.

So, that cpu-Z pic..I can get 4772 max @ below 100, and above, but it also requires differnt multis as I scale the blck up, yet the max frequency doesn't change.

random said:

Yes/no. it's quite nuanced, and small bclk changes affect frequency a fair bit, and it seems very dependant on memory multi used, too. In regards to voltage, speed, etc, my two chips are very different, but the blck/multi thing doesn't change too much between them...

Frizz · Apr 28, 2011

Well I set bclk to 100.2 in BIOS and it seems to be giving me 100 now in windows

EDIT: Hmm, setting it to 100.2 just renders my system unstable it starts to do that annoying BSOD while idle thing again >.>... I think I will leave it at default settings.

Great. Shouldn't happen, IMHO signs of an immature bios. i got rid of BSOD by using Turbo to clock, currently working on UD4.

Hmm well my CPU PLL is off and 4.5ghz is the highest I can go with it off (I am using 4.5ghz atm), but when I use a higher BLCK 100.+ on easytune the clocks seem to spike higher than set multi (45) I am not sure how this affects stability but all I know is that when I have it on default I don't get BSOD.

I will play with turbo clocking and see what results I can get. Could I possibly get a OC template from your gigabyte board if possible?

Yes, for sure I'll toss up my settings when I've got them all figured out. Just working on clocking the board for my review; it just arrived a couple of days ago. Today I'm clocking, will spend the weekend gaming on it, then I'll be writing early next week and hopefully the review will be up before next weekend.
