[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 1189

post #11881 of 12080
I'm running it through IntelBurnTest at 3.2Ghz stock voltage so far passed 6-7 out of 10 on 128 threads maximum load memory 4GB installed atm. Cores hit 49C. 39-40C load at 12v cpu fan, though I wired it to Molex +12 / +5 for 7v quiet adequate fan.

It's scoring 320 roughly Cinebench maybe 350 without any voltage and way below stock clocks on Northbridge/ Hypertranspot... 1700/ 200 vs when I get AM3 760G lined up hopefully upwards of 2500/ 2500 and 4Ghz so until then this is what it scores on the crappy board. It performs great though, faster in applications like games than LGA771... With it's 10 1/2 to 11GB/s (DDR2) memory copy vs 6-10GB/s LGA771 DDR2/DDR3.

According to my math it will require 4500-5000Mhz core clock to pull 500+ Cinebench R15 just like the Xeon.

Which was your score at 4,7ghz??

I have DDR2 memory set to 1:1 @ 5-6-6-18 2.1v.

My FSB is at 470MHz for 4.7GHz oc & your FSB is at 474MHz?

With my Q9550 @ 4GHz i got 430cb,that was on 471MHz FSB.

I wonder how this stacks up to the X5470 & X5492? When running the same core clocks mind you this CPU is still 11x under it's HyperTransport potential of 2200mhz... and 22% below it's stock Northbridge clock. I mean this thing is performing beyond the theoretical max of DDR2 memory... 3.2GB per module/ 6.4GB/s in dual channel... I actually hit 12,200MB/s memory read before blue screen haha wink.gif



I can't find X5470 X5492 Stock AIDA64 CPU Cache & Memory Benchmarks... I did stumble across this... Had to take a 2nd Glance... Like What-The-Heck? haha 6 1/2 TB/s and Hundreds of Gigs per second Memory haha

Here is my X5470 @ stock 3.33GHz & @ 4.7GHz!

Xeon E5440 @ 1600MHz FSB = Xeon X5492

^ I can't set 900MHz RAM frequency because I don't have divider/multiplier for it.
Next is 1000MHz, and 8GB of RAM on P5B "Vanilla" is a no-go with that speed.

Few things worth pointing out :
Quote:
...mind you this CPU is still 11x under it's HyperTransport potential of 2200mhz...
1) Hyper Transport connects CPU to Chipset (like 790FX), which houses PCI-e controler (ie. useless for CPU/RAM performance).
If you meant HTT clock, it's as useful as BCLK in terms of performance.
Actual NB/CPU/Memory multipliers count more than bus speed itself.
Quote:
...22% below it's stock Northbridge clock...
2) ^Now that is plain stupid.
NB clock is IMC clock, so I guess you clock IMC slower to showcase how good it is ?
You really like to troll don't you, can't you set best clock for IMC you can (I thought that's the point of comparing OC'ed CPU to stock one) ?
IMC inside CPU MUST be faster than Intel's IMC in North Bridge - DUH.
You don't have to brag everytime about it everytime you mention your Phenom II CPU.

3) 3,2GB/s and 6,4GB/s in Dual Channel is effective bandwidth of... DDR1 at 400MHz.
Math is hard, I know wink.gif

That 12,200MB/s was done on 930MHz+ memory effective frequency I assume (based on screens you provided in attachments) ?

Ummm,I hate to say it Chris,but he's got a point.I'm waiting for a post saying "Wow,this Opteron started this morning and a xeon would have been questionable because of the memory speed"rolleyes.gif You REALLY need to be posting all this wonderful info under the AMD section. Last I knew,that Opteron build wasn't involved with a socket 775 mod.(Although,If you DO get an Opterong running in a moddified socket 775 board,PLEASE post it here! thumb.gif )

Yes keep AMD separate from this 775/771 thread please.

I have my X5470 @ 4.6GHz now with 1.47v,i am happy with the temps,4.7GHz will not be possible now,summer is coming,will be hot as hell.

I have 3 profiles in bios:

-4GHz at stock volts(1.23v)
-4.4GHz at 1.3v
-4.6GHz at 1.47v

4GHz will be used mostly.

Also i tried to see if now with my new PSU i can overclock my RX 480 higher & yes i can,1500MHz Core Clock! thumb.gif

My X5470 is STABLE up to 4.6GHz,cant test 4.7GHz due to temps.
