I just built a AMD 64/Pentium 4 3.2EE KILLER!

[GigaHertzAddict]

what speed is your 9800p running at?

i want 6.6k

cant wait till i get an m0 this xmas

edit: also whats your vdimm and divider set to?

435/370

My memory Voltage is 2.85v at 201MHz 2/2/2/5 (3:2 divider)

Although I don't need 2.85v, I'm just testing it right now..

 

[shortbus_]

get that ram up to 240MHz so you can run 5:4

It won't run at 240MHz.. no matter what timings I use..

 

[climbski]

Hello.. your system looks quite familiar as does your FSB limit

I was stuck there until i used clockgen to increase the AGP bus to 72/68...then I used it to increase FSB...

Do the vdimm mod using smd grabbers as outline in the excellent sticky under ASUS Intel mobos...5:4 shoul be doable then..

 

[GigaHertzAddict]

climbski, [BBE]Jimbob and Reverse.. THANK YOU SO MUCH..

Clockgen WORKED.. right now I'm running prime at 303MHz Bus speed..

I think I'll be re-posting my benchmarks.. THANKS AGAIN

What Voltage are you using of your CPU to get that high? In the bios and at load. I like using 2/2/2/5, I think it's more important than 3/4/4/8 at a higher MHz... But I can always try the voltage mod..

 

[climbski]

You are correct 2-2-2-5 is critical for 3DM01 It is sig faster than CAS2.5 or above even running 1:1 (not possible anyway at 300FSB+)..and all real world usage...3.45V at 245mhz

Also my 3.3V rail is adjustable to 3.9v which is important when needing over 3.3vdimm.

 

[everclock]

So you tried popping off the IHS on that M0.....haha, do not try!!! I saw an unsuccesfull attempt, it looks like the IHS's are soddered(sp?)/glued on to the m0 stepping, but nice overclock, I am def. jeolus, then again, i dont even have my p4 system up yet.

 

[batboy]

I'd like to know more about the 3.3v to 3.9v mod. Can it be done to the IC7?

 

[climbski]

Has nothing to do with the Mobo.. it's a PSU mod for most people.. I'm lucky though , my PC P&C has an internal pot that allows me to adjust the 3.3V output as far as 3.9..i only go as far as 3.5 for what I need though.

Dunno if it would help on the ABIT ..probably.. (although I've heard the vdimm mod on that board is difficult which is one of the reasons I bought the ASUS)... most vdimm mods on boards are only limited to the max of the 3.3 PSU output. Once you've done the vdimm mod and increased resistance to maximum your VDIMM should be nearly equal to the 3.3 rail.

 

[pacino]

climbski, That's awesome!!... adjusting vdimms on PSU? heh... I want one of those, what brand is it?

They were always "glued" on. I'm not sure they can sodder on a PCB maybe the person who performed the procedure messed up.

 

[batboy]

I'm with Pacino, I want more info about the adjustable 3.3v power supply rails. Wonder if my Antec True Power has that? I don't see anything about it in my manual. What brand power supply is this?

By the way, the IHS is epoxied onto the CPU core (not soldered).

 

[climbski]

I don't believe the ANTEC true powers (except thier top 550W PSU) have adjustable pots for the rails...take the cover off and see though. My PSU is a PC power and cooling, turbocool 425W which has internal pots.

There is a way to make the Antecs 3.3 rail higher however. Here's a Pic I found...hope you can decipher it. I didn't have to do it so i'm not much help

Hey I asked you before but you didn't seem to see it, What voltage are you running your PC at? In the bios and a full load. Also what cooling are you usning and what are you temps?

 

[batboy]

Thanks Ski. I do have the Antec 550 True Power. Guess I'll pop the PS casing off and take a gander. If some electronic whiz can decipher that diagram and put it into simple plain English, I'd appreciate it. I'm assuming the 1k ohm VR is an adjustable pot. What is the other 10 ohm thing? Perhaps a resister?

 

[pkrew]

I'll probably get soundly booed for this and maybe even flamed. First let me say that you have a great overclock. Unfortunately its not a AMD 64/ 3.2 EE or for that matter a well setup 2.8-3.2C killer. My system runs about 150mhz slower and 53 slower on the fsb and I beat you on every benchmark and that would be with a 9800pro not the XT in my sig. I'm not trying to brag, but to make the point that the quickest P4 systems are the ones that are able to use a memory ration of 1/1 with tight timings. If you want to run 3.5G then use a 2.8C, a 3.0C with be the best at 3.75G and the 3.2C will theorectically have the best overclock at around 4G. Right now the 2.8C only cost about $30 more than the 2.4C. When I had a 9800pro and running at 3.39 I would get around 7200 in 03, over 22,000 in SE, and 40s in superpi. I don't remember my cpu score but memory in PcMark was around 11,500. At the present fsb memory is 11650, and superpi is 39s. I realize that a lot of people think the 2.4C is the best overclocker, but for 30 more the 2.8C gives you a quicker system.

 

[climbski]

CPU is 1.75V in bios about 1.7 actual
mem at 3.5V
agp voltage at 1.7v (to stabilize the CPU voltage)

cooling is a SP-94 and 92mm Tornado (actually overkill for my speeds and voltage)

Yes this type of stystem DOES kill the 3.2EE due to it's weak FSB...My score 9800pro score probably beats your 9800XT score...see sig

It will not beat a well OCd AMD64 or FX with similar cooling however.

AFAIK I have the highest aircooled Intel (non Engineering sample) 9800pro score for 3DM01 .. at least i did a few weeks ago.

 

[Jimbob7]

how about you two have a fight out loadsa benchies and stuff wuahaha this could be fun

 

[climbski]

Actually it would be fun... I am sure there are apps where the xtra cache would be better and I know there are benches where the High FSB is better (3DM01)...I'd be up for it...if someone could host some screenies for me...let me know if your interested pkrew.

Shall we keep it fair say 3.6ghz vs 3.6ghz? 2-2-2-5 mem timings (if you can run that)...obviously FSB and divider will be different.

Or shall we just go all out top OC vs top OC...Hmm what cooling do you have? I'll even take you on if you are watercooled...as long as you don't chill it below freezing and I can use cold air if you do chill.
