Can you give us some real impressive 25hr Prime95 clocks now :banana:

2.8GHz+ I mean :D

I was going to drop down to 1.648v but decided it was more fun to stay at 1.67 and redo the burnin at 2.85Ghz instead of 2.81 :) Lets see if I can get that stable before dropping to 1.648v. Hmm. Last night prime ran for 4 minutes. Now I get 6. I do notice benchmarks went up. I was getting 5740ish in pcmark2004 last night (stable 2.81 gets me 5713). Now I got 5803. Superpi 1m dropped from about 29.65 to 29.39. I think I stopped short last time when it got to the part where it became less stable.

hey dont forget prime and OCCT for the complete burn in. ;)

i just ordered some UTT BH5 (OCZ EL Gold 3200). I want to test this theory out of needing lesser voltage (VID wise) and getting higher clocks (cpu wise) with UTT based memory on SD cores.

Will report my observations once I get the ram.

wish me luck:)

longing for y results! i m one of those who believe that SD cores show a strange preference to some type of memory. Of course it maybe is a bios related issue and not related to the SD cores
good luck of course!

yeah i think its ture.my vx with this 3700sd only need 3.45V to reach 260 1.5-2-2 whereas with the 3200 winchester they needed about 3.55V for same.

Test and list your memtest BW @ teh same FSB x multi (don't have to use the max values for this comparison either - easier :D ) and same timings.
I find that Vdimm seems more related to BW then just FSB (chips will need more Vdimm if mem ctlr runs more MBs/sec through @ a given setup).
:toast:

I believe the SD core doesnt like TCCD ram much. I have same ram here and it wont remain as stable as it did with my 3200 winny. I think its going to take some bios tweaking to get this all working right IMO.

I got a 3700 last week. Great chip for Vapo or water cooling.
First I tryed at my friends house on his Vapo LS. We where running 3D at 3300MHz with only 1.5V.

I then put it on my -90C cascade and DFI mobo. I had problems, the board wigged out.
Then I switched over to my MSI SLI mobo and there was no problem with the Cold issue. Although I did have to use W2k and Ricky tweak though. It would freeze up in my XP OS. Problem with the MSI is that it has problems going high FSB, 300 was almost impossable.

I then put it in my everyday DFI Swiftech watercooling rig. Overclocks nicely, I run it at 336x9 3025Mhz 1.45V. That 336 is running 1:1 1T by the way. I have some killer OCZ memory here:D

On the DFI Swiftech of course

I use the 1.25 Bios.
I run 2 seperate raid setups on this rig. 3x Raptors and 2x Some other kind of sata drives, forgot the make:D

I Love this rig.

I left the vcore at 1.67 and upped the speed to 2.85Ghz. That was enough for about 4 minutes in prime. After running toast all night prime ran for 6 minutes. I'll try again tonight to see whats up. I was about to run 4 burnin programs at the same time but that locked the system ;) If this works does anyone see anything wrong trying 2.9Ghz before lowering vcore? :slobber:

i wouldnt try to burn it that way. that overclock might be your ram making it unstable who knows. so run a clock you know works 100% stable, then lower the voltage until its just enough to boot into windows and run a app..then burn it for 10 hours or so!

remember, it may actually take a week or so of over 10 hours a day burning before you notice any difference

Its running right now @ 283x10 1.55v, its still stubborn past 280x10 .

Push it as far as you feel safe! Mine barely boots into Windows at 2.9 so I can't help you there.

Good Luck!

Hmz... Haven't seen my "burning" question around here yet: It it better to "burn" 10h/day or burn in 24/7 once? :D
When you do it 1/day you'll maybe drop the voltage after 2 days and burn again? Uhh??? :p:

You can always bump the ram down to 100Mhz :) Usually memtest fails on me pretty quickly if I go off too far.

On my old Clawhammer I would exit out of prime after 2-3 minutes ;)

I have been doing it for at least 8hrs at a time when I am not running Prime.

As to if you might benefit longer? I ran it 12hrs max so far, but 24hrs might benefit you. Or you could ask Sentential i'm sure he has already tested it.

*subscribing*

This is interesting. I had always kinda thought of burning in like this to be kinda like weight training... but lack of patience always had me upping the volts until it got stable, rather than running bare minimum volts and MAKING it be stable.

Toast'ing at 10x280, 1.475v * 110% (1.6v in BIOS, 1.58v in CPU-Z). Running for an hour now, and no blue screen so far. Will let it run until this time tomorrow, and then see how long it'll prime.

here is another bit of advice on burnin. go say 10 hours or 12 hours on bare minimum that will boot into windows without immediate crash. then when that time is up, reboot and try to take it down another notch. if its stable enough to burn it at the voltage, try another step lower untill you reached bare minimum again. then burn awhile longer


does anyone know how brittle the core is with the IHS off? is it like the old aXP cores or is it more brittle?

-Jordan

That's the max I've seen. I saw a 3505 on the forum. If you can get that screenie, I would think you would be able to get a little more out of your superpi max (great score BTW). I think the best screenie I can get is around 3430 or 3420, but I can pass superpi @ 3339mhz.

Turbodream, that's a nice score you have there for your cpu clocks. What's your VC at?

I think it was around 1,73V

What is everyone getting prime stable on single evap?

I`m at 287x11 on a Vapo LS, 1m SuperPi stabil, and runs most 3D benchs at 291x11 for 3.2GHz, I don`t run prime95 much anymore.

im using vapochill PE currently at 265 x 11 stable. Still more in it though just trying this burn method now. My 3700 was prime stable at 2920mhz at 1.52 volts out of the box but wont do much more even if i up the voltage to 1.7.

http://suckasd.com/computer/sandiego/sandiego.jpg

That's the highest max i've been able to find, anyone know of a 3700+ higher?[/QUOTE]




Sucka what is your CPU date /stepping???
