You do what you got to do to get the clock speed where it really matters anyways..ram bandwidth not as much as timings...if he can hold 1t then he doesn;t take that hit so he probably at 2.65ghz can hang with my system at 2.57ghz.... think he would be happy....Since he couldn't get to 2.57ghz without using the 100divider...


If he can hold 2.65ghz at 1.57v range means you likely are stable at default vcore in the 2.5ghz range....That would put it on par with my cpu....

Well SuperPi finished in 30m 28sec @ 2655.

System defniitely seems stable so far @ 1t as well..

Yeah, I got about the same results... but with RAM at 217, and my CPU at 2475 with my Winnie, it finished in about the same time. So the ~125 MHz gain in CPU speed was negated by the running my RAM at 186 MHz instead of 225.

I would agree..

Patched version?

Actually I saw no difference between the patched and non-patched versions. There was a small difference, but so small that I'd say it's within the acceptable margin of error.

*EDIT* I saw more of a difference by running it on my WinXP x64 preview installation... I think that finished a full minute faster.

Jeff what voltage are you running that 3500+ Venice

Really thinking of going for 2.7 stable...

1.5... I'm pretty sure I found the sweet spot at 2.63... if I go higher, Prime 95 fails the Small FFT test... if I reduce the multiplier and try to go higher, it fails the blend tests. More voltage doesn't help anything.

That is interesting cause I know I shaved off 1 minute off of my best time at same 2.64ghz with same memory divider and timings.....The patched vesion gives me 1sec faster in the 1mb test(0:31 vs 0:30) and 2sec faster in 2mb test(1:14 versus 1:12)...in the 4mb test I was 5 sec faster and it ultimately grew to that I originally has 29min 04 sec and I dropped to 27min 58sec.....I will have to find my screenies cause I know I took pics and showed them before.....

D,

295x9 is definitely where it's going to stay at.. Been running Prime for about 6 hours now with no issue...

When I jump to 297 I error out ( wonder if it's a memory issue, getting flaky)

But 2655 is rock solid @ 1.56v



I really would like to see a lot more 2.8's and 2.9's..

Guess we will have to wait it out.

 

[Duvie]

I am happy you got that...Should be much better then that 2.17ghz you were getting...

6hours is pretty damn good...Any failure really after this point will likely be memory related as well...How are temps??? mid 50's still???

 

[Duvie]

Go ahead and run memtest for windows and memtest dos version and test #5 and #6 and see if it handgs on....I have seen prime stable 8-24 hour setups get a BSOD and even an Early End Unit in Folding.......I would go for 50-100 passes of each test and maybe 10 passes of them all...Along with 10 passes (1000%) in the windows environment and then I have never seen an issue after that.....

 

[bjc112]

Thank you sir.

Plenty thanks to you and others.

Actually 50C.. Bumps to 51 then 49..

Pretty impressed.



Do you think that its possible my memory could still be holding me back?

Because around 300 my memory speed is about what it was @ 240 (166 divider)

I could NOT post @ above 312 or so...

Or do you think the chip is just about maxed.. ? I guess it more likely to be the chip at this speed.


I might be able to get my hands on some XMS this week, maybe I'll try that..

I am still very curious about puttin the CBBID back it, it might have 2400mhz in it with the 100 divider!

 

[bjc112]

I know SiSoft sandra isn't important, but what is everyone else scoring|?

From what it looks like to me, it seems you two are having motherboard/BIOS issues more than processor issues. Am I correct?

I'm not having any issues now..

But before it was more memory issues than anything.. It could be the way the Neo2 handles it as well.

 

[bjc112]

UPDATE 5/23!

Sold me 0516 to a friend, went to a 0515 LBBLE and now am sitting pretty @ 2.8ghz

OCZ @ 2-2-2-5 1T

Voltage looks good @ 1.55v

Temps are awesome!

 

[bjc112]

Prime still going strong!


2800 after about 12 hours.. Not going to stop it yet..

niiiiiiiiiiice overclock man, good to see some 2800+ venice OCs here

Thanks, it's a 3000+ though..

 

[Dadofamunky]

Monster OC for a 3000+. :thumbsup:

 

[MegaWorks]

WOW! the Venice cores are the new T-BRED B DLT3C 1700+.

Yep.. That was my previous chip!

Go AMD!

Trying 315x9 now.. I think my board is starting to get flaky.. Going to try and raise the voltage on the NB..

I can't see how 2850 can be completely unstable, but 2800mhz is rock stable.. Gotta be the board!

 

[Duvie]

The true way to test that is drop to a 8x multi and run 315.....At that speed you should do it with stock vcore easily....so leave vcore alone and if it doesn't do it you will know...make sure you drop memory multiplier to take that out of the equation.....

Will try.. Going to run prime for a few more minutes.. Just passed the 1024k test @ 315 but failed instantly @ 318

Memory ran memtest for 4 passes (even though not long ) @ 320 (217mhz 2-2-2-5) 1T

BTW: I am down to 512 now, my other 512 stick of OCZ was defective.

 

[bjc112]

is 1.65v safe for AGP/NB voltage?

 

[Duvie]

I wouldn't go into the red on that category in case it may effect the agp and the vid card....I dont think you will gain anymore...the NB chipset needs to be pulled and some AS5 applied before I would try any higher and expect anymore....

Most guys who have hit 335-340 on the Neo2 boards removed the NB chipset HSF and did what I said....

Ok, well 1.65 is still yellow, I'll give it a shot for a bit and see if I make it.. AS far as popping the NB fan off, does the board need to be removed?

 

[bjc112]

Wow, the chipset fan EASILY pops off, but it looks like the board has to come out.. There is next to NOTHING as far as paste applied to my dead board, No wonder I can't get above 315..
