Are these your results with the IHS removed?

I take it you have one of the SPMW ones as well?


I'm trying to see if I can find anyone that might have a TPAW. I doubt the OCing potential would be too much different from the SPMW but it would be nice to see some results for it :)

I quoted my full code in previous posts, but here it is again.

A different stepping result would be interesting.

And yes those are with IHS removed and watercooled, although I need to strip and check I have good core contact and maybe change to AS3(from As5) as I always have had better/consistant results with AS3.

I do think that 3Ghz is possible as I can run a whole world of benches, but its not stable (as yet)
 
Its a little bit of a combination.
1: IHS is not perfectly flat - infact i would go as far as to say its inferior to the STD AMD HSF. Generaly they are Concaved (from what I have seen lapping them), so they have higher edges. This is not good and dispells an ytheory about pressure used to get a better contact against core etc.
2: The TIM under the IHS has a thickness to it, might be only 0.1mm but its not good, nor is the fact its seems cheap stuff
3: Its just another thermal junction , and junction acts as a barrier and requires a slightly higher differencial to make the heat pass, the less we have the better we cool.

It all goes back to the Celeron days realy, we used to pop the caps back then and direct cool , then we did it with the P4 (except m0's) and now with the AMD.
It does stop many problems with core crushing for many, but waterblocks dont excert as much force on the Die as a HSF clip, nor does it require a side loaded clip.(with some exceptions)
I dont even use springs, i just clamp down. Always have done.

but does it really make that much difference off?you're o/c are pretty much same as mine and Concorde and he is aircooled.I also think phase change would show true voltage scaling with these.but im hopefull with some burn in the 3GHz barrier is possible.

so ive setup prime95 as max heat/power consumption(100% cpu) but custom so 1Gig mem is tested too.Going to run this overnight so should serve to burn in cpu and VX. ;)

Well you say that, but you 2 might have slightly better CPU's then me to start with. Rem not every IHS will be as bad or good as the next.
BUT I know my system is 100% stable, I can run anything at the settings I quote, for extended periods of time. I can bench well into 3Ghz, but I just can't get it stable, as said I might gain from a re-seat.
CCT in torture test is awsome, its soo stressful that the slightest querk will show up. I like prime95, but its outdated now IMO.
GO does bring prime back into the game, but hardly anyone uses it.
So although my gains don't look great to you, its still probably 100mhz more then with it on for my setup.
 
Just so you know, I did'nt read it as hostile - so no appology needed realy.
I am all for deating things, but I would'nt pop the cap off a £200+ CPU for no reason if it was not worth it IMHO.

I can walk you through it and maybe host some pics if you feel the need, but basicly its as easy as stanleyt knife and slowly work in at each edge, not too far though, say 5-6mm, then slowly slide the blade accross to join each corner up. 3sides and it will fold off.

anybody found any util which lets you change the voltage in windows on ultra-d?
clockgen does nothing and CBI just crashes windows.its a pain in the ass trying to fine tune o/c having to go back to BIOS each time.
Click to expand...

Clockgen would work if you dropped the start up volts and used the + 123% and over settings.
 
monkeygabriel said:
ahh so set the start up to minimum and choose 123%?then clockgen will let you raise or lower?im talking about raising from 1.45V up, wont 123% be over that already?
Click to expand...

Yeah, clockgen will only let you use 1.45v max (this is STARTUP setting, not actual), so use a startup of say 1.2v and the +123%(or whatever value you want).

I have tried this and it works.
 
monkeygabriel said:
ahh cool mate, will do that on next reboot.this OCCT test is a fussy bugger.had to drop back on clocks to pass but now after doing so last night and today(the joys of a wekk off work ;) ) im able to get higher stable o/c with it.do you use this to check stability?its much fussier than prime95, i never thought that possible. :eek:
Click to expand...

DO I use it ? who do you thinks been pimping it all thread ;)
 
You ALL should be using a combination of S&M and OCCT, I have already gone over this in previous posts.

One is not better then the other as such, they both will test in a slightly different way. SnM does have the ability to show what part of where failed, but OCCT is far more twitchy about settings.
 
510 versions have some problems with SATA drives.

For TCCD you should running 414-1 or 510-1 anyway
BH/UTT is 414-2/510-2
and the general would be 414-3/510-3 ( these are the version that get official releae based on)
 
monkeygabriel said:
nah definitely a 120.2 matey still better performance and when the fans are low one is as quiet as two or vice versa unless you stick your ears inside the case.

what case have you got btw?
ricco should these posts be in the watercooling threads?:p

Dont be so pedantic, and yes they should as its just fills the thread full of ****** with no relevant information to 90% that post in here.

etc
etc
;) :D
 
monkeygabriel said:
oops the boss has spoken.sorry boss no more o/c posts in here unless related to new BIOS etc on the mobo. :p
lol your choice of words is perfect(load of ******)lol.

AH the ironies. :)
 
Concorde Rules said:
Ah this is just taking the Pi**, 262x11=2882mhz super Pi is solid.

286x10, 100 passes memtest test 5 and super Pi doesn't even do 1 pass.

Im really annoyed now :( Some excellent TCCD doesnt work, however, I will try looser timings after 2.88Ghz 32mb Pi has passed.

Concorde <-- sad.

Keep at it m8, its bound to be just a setting problem.

Ok , tried it with a set of XMS4000 I've had running at 250 for over a year now, wont work, get memtest errors and am unable to boot into windows at any speed. This seems like a CPU/Mobo problem after all.

No mention of the BIOS version your running.
You will need BIOS 414-3 if you have'nt got it already
 
TBH I can't understand why you would want to run win98, very minimum would be SE and I would'nt recomend anything older then win2K.

But back to your problem.
Please read the very very first post, it has a lot of info in it.
As for power button, check to see if the onboard power button works ok, might be faulty case switch - i have had this happen.

Your mem is Hynix D5 btw.

Again BIOS 414-3 needed IMO
