SandyBridge 2D madness - let's tweak for the best 1m, 32m, pifast and wprime!

[Splave]

bought 3 new chips from the egg
1 is a 5.2 stinker
2 is a 5.5 1.58v 32m 5.6 boots into windows havent played with it that long
3 is running 5.6 1.635v 32m

not too shabby

Like cheapseat said gtx2 is faster than blade for almost 0,5s ( on same settings ) , will try to get gtx2 so I can compare myself.Also will try another bios just to see if anything changes in efficiency.Just got this board from store few days ago, no time to play seriously yet...

@Splave what batch/SN ?

[C-N]

Dont know if its any use to you but I just uploaded the GTX2 SPD if you want to try it

Yesterday and today tested six 2600K L045B387, one of them could boot and did wprime32/1024 - 5637MHz, another one boot only 5400. I tested with water cooling, when i found 56xx MHz chip, i changed type of cooling and used SS.
So I tested 14 - 2600K, 5637 was the best. The friend of mine tested 3 - 2600K and 3 - 2500K which he bought in USA(I bought all 2600K in Ukraine), the best was 2600K 54xxMHz, and one 2500K we won(Nick and I at MSI MOA Ukraine) =544x MHz max So guys who found good chip and didn't buy at least ten cpu's are lucky

Actually I figured it out....didn't realize you used a 2500K. Less cache is what cost the performance hit.

Yep its really really lucky to get even 5.5Ghz chip -.-
This first 2600k of mine is L039B470 and maxes out 5480-5500Mhz. Once i get it stable on superpi with SS i can run Wprime 1024 at 1.5v@5.5Ghz.

But that speed isnt enough when ppl got over 5.8Ghz chips
Gonna buy fev more and try my luck! Happily i got more platforms to test with LN2 soon!

2600K

#1 5400 mhz
#2 5260
#3 5370.

I am currently out of luck.Ill try again after 1 month,maybe new batches appear,or my luck will change?

Awsome tread guys , wooow i just finished reading the whole tread and it is an open book for learning , thanks for sharing the knowledge guys

Now that is nice!! You finally find good hyper kit and board which is working with it. Waiting for final score

[Perica_Barii]

Good result... What memory did you use and vdimm , for those settings ?

Got a 56X Chip out of the first 4 I tried but after that it has been a long uphill battle. Have tested more than 30 chips after the first 4, and none of them have been able to match my earlier 56X chip. Best I have found out is a 55X. Got even a CPU with SN# XXXXXXXX300 which with earlier generations mostly would have turned out to be golden but it was just a 52X chip.

Thankyou Filip!

Perica, those are 2000cas7dominatorGT 1.775v. 2133 only needed 1.725 subs are pretty tight though

1485 worked better for you i guess

hm..not good. my last shopping: 4 * 2600k from amazon. 3 of them can 55x but only 5550 max. and the fourth one can x53 and 5360mhz. its only luck not more. so i've tested 8 peaces of SB 2600k and my best do 5550.

bios? and green or black pcb?

nice how much vdimm?

im amazed that they're not dead yet

Well done Aristidis and matose! Actually I think that Aristidis's run is the fastest @ 5GHz using PSC/BBSE chips

chip will not do 32m at .1bclk higher no matter what time to work on subs
