***955 Unleashed***

[cdawall]

ran into issues with XP didn't get a chance to run any 3D benchmarks but i did manage to murder my copy of XP

omg....whats your cooling cdawall???If this with Air/watter, congratulations'!!!!!

Its DI

rubbish...every reviewer I work with said the same thing as i have.

I needed higher voltages to have 100% stability for same clocks within Vista 64 period.

both my CPU's are good, nothing wrong with them. test with a 955 and you may find the same.

Maybe Vista is one thing but W7 64bits vs Xp Sp3 32bits i dont lose any mhz....so trust me its not rubbish i have tested it many times becuse i dont want spend any more money on a new cpu so i make many test with the cpu i have instead. And dont tell me i´m a newbie then you geting the wrong dude.....but all can make misstakes thats true

And i dont trust reviews...many times the abit wrong from the real world.

But you did say 64bit vs 32bit in your first replay and not Vista 64bit , so it can be a point there with Vista.

But you can always send me a 955 so i can test it


Edit: Did a fast super pi1m in W7 64bits @ 4.0ghz with 1.47v without any trouble....to bad i need go to work now but i will post it later and more test for you Tony.

first test...

Batch plz.

Well I can share my experience...I can do the same 3.7 or 3.8Ghz with 4 cores on my 720 in either Vista 64 or XP Sp3 without any changes and stability is the same.
Then I try Windows 7 and it will blue screen. 3.6 is the max I am getting stable under Windows 7. I didnt bother trying to give it more voltage as I saw no point to it.
Regards

Had major stability issues in win 7 as well, couldn’t even get 3.6 to run stable. Have to give it another try further down the road, when it’s a bit more mature.
But I see no difference between XP and Vista 64, although I can’t really test it accurately on this board.


And nice clocks chew, as always

Wez was the 32 or 64 bit?

We wil be benching either vista or win 7 32 with crossfire X 4870 x2's (whichever gives us better results) however we have already near matched our XP speeds......we had to back of the NB clocks 200 mhz.....in win 7 before and that was it.....core clocks remained identical with identical voltages.

Early Am and still at it, getting prepped to test 4870x2's out......I think any power issues we may have had are a thing of the past ..........

It was the 64 bit version I was playing with, never tried 32 bit win 7. Might give it a shot this weekend and see if it behaves any different from 64 bit.

That’s a nice little pile of PSU's you got there, should be enough I recon! :P

Batch plz.

will post tonight. at work atm. 0911 cpu though

prime is a nogo currently at 4gig.. but we will see...

Thats why High volt d9's are not my cup of tea to bench with cold.....I'd rather take a small performance hit and bench 16 hours straight with a set of rock solid stable sticks rather than to waste DI or ln2...

Not to mention that they ( D9's ) are known to Bug out when cold.... now you know why I didn't bench LN2 with them and why I only pushed the ddr II d9's to 599 instead of higher...I should have backed off them more......validations would have passed........on phase and DI.

[F@32]

Ahh but you can say its better is some things man....I get my butt kicked by cinebench in 64 bit, sick numbers, I just wish all apps were across the board faster......that would give software co's incentive to code for 64 bit.....at that point I would make the shift.

QFT. Sorry for taking this further off topic. I just see no reason in 64bit OS until there are apps I'm interested in (games) are 64bit and run faster because of it. Never seen any game requiring more than 1.5Gb of RAM. 4Gb in XP SP3 works very well for me.

Back on topic. 955 looks like a beast. Would have switched if I had slow CPU.

[JoNo216]

Awesome results! I hope to be able to pick one of these up later this year (if I can afford it)!

10 min prime 64 stable acc +8% but bsod'd soon after.. this is taking too much voltage for 24/7...

[Lastviking]

64bit is hard on these CPU's when overclocking, voltages need to go up and heat output rises also.

I tested 64bit and lost 200MHZ as same voltages to 32bit...there is work to be done to make thing equal that's for sure.

I like 32bit though as i TRIM the vertex no sweat LOL...I like things fast all the time

"ok" here is the image....And YES maybe Vista 64bit is harder but it dont looks like W7 64 bits are than Win Xp.

I will not install Vista and test.... W7 works fine for me



And this is not the limit i think... it was a fast test if i remember right 4060mhz was max in Win Xp 32 bits, if you realy want to know if i can do same in W7 64 bits i can change the clocks for you


Sry for OT!

temps and have you tried less voltage? I found when I first played with these I was used to chips requiring higher volts.....I backed off volts eventually and it was smooth sailing from there.......Optimum temp range for prime is under 50C...

I know with the 940 no matter how cool I got chip it electrically it could not pass prime at 4gig.

Also you will want to do this with ram and NB and HT backed off......eliminate everything from the equasion......thats how I test cpu's, Once you know cpu can pass you work on everything else individually until it starts failing.....this makes it far simpler to diagnose individual problems...



Lastviking the key to your 64 bit stability could certainly be the fact that you are running 800 ram speeds.......Might be on to something here.....

[Oese]

temps are around 50°C core and 45°C board cpu diode.. i will lap this thing of course

i tried less volts but not with -% acc perhaps that'll gonna help some..

right now prime runs at 3.8g @ 1.425v.. nice as well..

damn i wanna use win7 as well, but my favorite game refuses to work *darn*

Somethings is not right with 1066 ram speed... i will try to figure it out, it will make WinXp crash after sometime and also corrupting files, thats why i have left it @ 800 speed now. Dunno know if its are the IMC, Ram, High vdimm or something else. But my sticks are rated 1066 2.1v 5-5-5-15

The 1066 speed problem started in WinXp have not tryed to change to 1066 and tested that in W7 yet.

You tried without ACC?

Sounds like a set of OCZ's I have?

I found they worked best on asus 5-6-5.

i have some HCF8's that i can toss in on the next run but i will for sure bring more than one copy of XP for my next set of benchies

[Oese]

You tried without ACC?

yep, without no worky.. acc is really helpful on this...

but.. i jumped to +150mV instantly.. will try 4gig again tomorrow...

[chew*]

Yah I have 2 hard drives set up with xp for that "oops" factor.

Really really don't trust high voltage d9 chips.....when they let go they really wipe out an OS hard....we were using the sammies at 2.0, they seemed solid around that range anything higher voltage wise and they got flaky....

Oese
Might be the difference in boards.......I don't even use acc.

[cdawall]

yep that sounds like my best bet. to be 100% honest the mess up was my fault we swapped over to a GB mobo and P4 just to see how the pot would do with it and from the moment it touched that GB XP was not the same
