is 4 ghz the world record for this processor or someone else is going to bit you i would like to try

 
3 raptors for a total of 350gb , 10,000 rpm --
 
not bad --got them at fraction of the cost in used ..and loving it
 

emmm how come they did 4.3ghz on this cpu ---i tryied my best but no way could i go above 4ghz -
 
if some one knows how to pls help out .

Most of what you see on hwbot are just max OC & not for every day use or 24/7 clocks.
Also you need to look at how many cores is in use on the screen shot.
By dropping cores you can up the multiplier. So say if your running only 2 cores you can
enable the 21 multiplier on a E5645. As I did here with only 2 cores 4 th enabled.
Look at the CPUZ screen shots of others closely.

@ guys with sr2 .
 
has any one been able to run aruna ray tracing benchmark on there sr2 ...its strange even with freash install of windows and all updates n all i still cant seem to run this benchmark.
 
where as other ppl have been able to run this program on there sr2 easily ..
 
what gives..............??

@ 4ghz but i did not slow down the qpi link ...
 
for some reason i think i h ave hit a wall either its the ram or the cpu cant seem to go ahead to 4.3 / 4.4 ghz .
 
@ wolf any help pls ..what to do ....
 
 
 

u used a blck value of 220 ---with 4 cores even ....i cant seem to go above 200
 
 

geting there slowly ..
 
nearly 4.4ghz

yeah thanks ....so do we get a new bios update or no..
 
 

First thing I would do is lower the CPU vcore voltage to 1.25v on all settings in bios.
Then up the BCLK until it becomes unstable, with any luck you will make it to 180/200 without any changes.
If you have some good CPU chips there will not be much need for a lot of tweaking.
Using the 18x multiplier & 200 BCLK that Will give you 3.6Ghz.
Try to reach this 1st then you can move on from there.
Wouldn't hurt to lower the memory speed for now so if there is a problem you will know it more to do with the CPU as the memory would be taken out of the equation.

No easy pictures aznd ALOGT of reading, but many tricks and settings

All those guys used the original screens... Got me to an easy 185 blk.
 
Saddly those boys are not way to advanced for a simple SR-2, and are overclock Supermicro 4p 12cores!

My es l5639 needed 1.136Vcore for 205blk in my ud3r, but with the SR-2 I'm using 1.3375Vcore or something like that for 185blk.  
 
Though I'm not finished tweaking, so it may come down.

I am having very poor luck with the o/c. Starting with factory default (A56 BIOS), raised all the Vcore  to 1.25V. Only changed the BIOS to AHCI, S3 and HPET.
Noted that CPU0 temp is 40C but CPU1 temp 77C. Have seen this before, carefully cleaned and reseated the waterblock with Arctic Silver 5, all fan connections check out fine. Boots A-OK into Win7 SP-1, all updated. E-leet 1.10. E-leet temps show nothing much high (PWM for CPU0 @ 45C, CPU1 44C, socket 40C). 
Dialed up the E-leet BCLK to 140, OK. 150 OK. 160 system freezes (all at default 18X, memory all auto per default setting). Did this multiple times w/CMOS resets, tried to set memory to 9-9-9-24 per Geil label, all Vcore at default, all Vcore 1.35. Had 12 stick of memory most of the time but also tried with only 3 sticks (red slots 1,3,5). No joy, totally frustrated at the moment and hoping for some suggestions. Note my rig:
 
EVGA SR-2, 2 x Xeon E5645, 2 x Corsair H60, 12 x Geil Enhance 1600 4GB, 
Gigabyte HD6870 1GB, 2 x Samsung 830 128GB SSD,  2 x Seagate 1TB, 
Lian-Li PC-76B, Seasonic X-Series 80+Gold 760W  
 
 

well i wana tear a new one for a guy here who has a rampage 4 extreme and 3930k---
 
hell he did 27000 in geekbench 64 bit and i cant seem to get even 25k ****f is this guys ...
 
24 freakein threads vs 12 and i cant beat him ..obvious his oc is at 4.7ghz ...i can do max 4 ghz but still whats holding back the scores .
 
his floating point score is over 40k in geekbench ..how to beat him .
