3.9ghz finaly stable

[jaguarking11]

Well I finaly managed to get my system stable at 3.9ghz. (will be tweaking for more)

Well it turns out that my old psu has been degrading for the last fiew months slowly because I downgraded its cooling in favor of a quieter psu.

Recently I was at my buddys house and he had a rather cheep psu (so cheep he got it free with a 20dollar case)

I picked up the psu and it was suprisingly heavy and stated that it was a 550w unit on its side with 22amsp on 12 rail. It looks like an enermax unit with no brand on it at all. I asked him if I could borrow it. He said I could keep it.


Well last nite I got home and pluged it in and removed my old psu. Man my old psu was steeming hot.

Well now my system is stable @ 3.9ghz and not only that but I managed to drop my timings from 3-3-3-5 to 2.5-3-3-5 while still ocing on the cpu 100mhz more.

Strange thing is that the source of instability seems to have been not the 12v rail and not the 5v rail but the 3.3v rail.


Just thought id point out the impoirtance of the 3.3v rail.

Friggin awesome JK11! What's your chip @ stock? 3.0C?

[jaguarking11]

my chip is a 3.0E lga pressy.

I actualy have one of the weirdes mobos around for it too.
Its an asus p5p800 thats a 865 with lga socket. So pci and agp not to mention ddr1.

Now the only problem is that my board undervolts on core allot. So after droop mod I should see 4ghz easy posibly 4.1.

my ram is very weird too, its (2x512) kingmax ram rated as pc400@ 3-5-5-10 and I have been runing it beyond pc4000 @ 2.5-3-3-5 @ 2.85v (260fsb) on it but it still runs cool so im moding it to 3.3v in the hope that I drop the timings some.

Here is hoping 4ghz will be possible after droop mod in a fiew days.:cool:

Btw star hows your abit coming along? What speeds are you running on it?

[Psykotik]

You should try the DFI 875p-T mobo, a mate of mine managed 4.6 Ghz on air with no mods with that beasty.

I managed 4.8 on water, but as is the way with my stuff, blew it to crap putting waaaaaaaaaay too much voltage through it.

Nice one man :thumb:

Ahh, a 3.0 toaster ;)

MY board is seemingly stuck at 312 MHz FSB x 12 (Mobile 3.06 P4) and the ratio is at 3:2. My chip stays plenty cool under load (talking under 40*C in winter) but I can't seem to go any higher on the FSB. My old 3.06 Desktop chip had the same problem... the board seems to top out at 3.6. So when I get my loop up and flowing again I'm going to take the plunge and voltmod the northbridge, which is, I think, the thing that's holding me back. I put my IR temp gun on it's heatsink under load and it was HOT.

funny you should mention that. Im about to borrow my friends dfi 875p-t mobo and if I like it ill buy it from him. My asus is pissing me off with the drooping and such. And im too lazy to volt mod it rite now as my life is geting more and more hectic.

And it may end up that the asus board ends up in my htpc machine with a nice little 2.8E pressy.

[Psykotik]

The DFI will offer stupidly good overclocking out of the box, I went from modded Asus boards to a DFI before I gave up my P4 rig, and the DFI was the one I managed to squeeze the most out of :)

small update on my situation.

My buddy actualy gave me 875p-t lanparty mobo. Now the mobo seems to be out of spec a bit as my adapted waterblock that fit my asus dosent fit on my dfi. I have a swiftech mcw5002-p modified with a zalman convertor to fit lga socket. It worked flawlessly with my asus mobo but on the dfi it goes over one of the large ceramic mofsets and wont fit (about 2mm more and it would fit) but when I modified my block I measured it to fit exactly on the center of the cpu and it does not have any wiggle room.

As for overclocking I hope it can take me up high when I hit water as im curently on a stock intel heatsink and I can barely oc to 3.5ghz. On another note the voltage options are nice on this thing. 3.2v on ram is certainly nice and 875P chipset with full on pat. cpu voltages are too high for my taste though. 1.9v on a pressy would eaqual complete death even under liquid nitrogen.

I am in a hard spot unless I can get another waterblock by mon hopefully.

just thought I would keep you guys updated. Here is hoping 4ghz+ after a nice waterblock.

good luck i think the power supply might have been what was holding me back before now i hope to get 4ghz too

yeh my psu is weak. it pushes 22amps on 12v but its very generic, but heavy suprisingly. Im thinking about getting a 500w 36amp x-connect.

[jaguarking11]

Ok a small update. I finaly have the dfi mobo running and still no 4ghz. still hiting 3.9ghz stable but not mutch more. Its not performing better than my asus mobo and it required I gring my swiftech mcw5002-p blocks side for it to fit as the parts around the socket are too tall.

Overall the quality of the mobo is not that gr8. I dont see why dfi is praised. Their mobo is sub quality to abit and asus in my opinion. It does run a bit cooler than my low end asus but thats about it. It does look spiffy though. The voltages are a bit stabler on the core now but nothing spectacular, it still droops more than I like (maybe its the psu).

Overall I am disapointed especialy since the mobo would require I grind my new used block I just aquired (polrflow cpu water block) and frankly I dont think it is worth me keeping this mobo as my main one. I will be modding my asus mobo and see where I go from there.

:-(

Oh and the dfi is a DFI 875p-t
and my asus is a P5P800

I can't wait to get R2D2 fired up with the Vapochill system. My 3.2 is gonna get rocked!

I would guess your 3.2 with a vapo is going to hit around 4.5ghz. If you charge it with r404a gass it may help you see 5ghz witch would kill just about anything you throw at it.

on another note
I was reading about the new dual core pentium D's and some people are getting their 820's to 4ghz and some are doing 4ghz+ with some good air cooling. It seems these chips are misjudjed.

[jaguarking11]

Well another update.

I got my hands on a 630 lga pressy and I am finaly stable at 4ghz. It feels awsome to have finaly reached my mark. I hear you saying (another guy whop spends all his cash for one good ocing cpu) and thats not the case. My father neded a new machine and since he will be running stock I put in my 530J and grabed his 630. I am also giving him my asus mobo and my ram and hes giving me his new (soon to be delivered) 945mobo and I have 2gigs of patriot ddr2 memory (yes its the low end stuff)

On another note, my ram is craping out at over 264mhz or so no matter what timings or voltages I push through them. so I am runing a divider and my mem bandwidth is about 5700mb/s versus the almost 6600mb/s I was geting when my ram was doing 267mhz speeds but unstably.

So I finaly hit my 4ghz mark and I am finaly at peace knowing I met my requirement and anything over this is going to be a bonus.

Also the dfi 875p-t has issues over 270fsb (its aparently comon knowlege over at xtreme systems)

thats all, have a gr8 nite/day guys.

[fivecheebs]

Good Job JK. It snice to arrive at a preset goal even if you do cheat a little ;-)

[Starbuck3733T]

The force is strong with this one :D

[jaguarking11]

I dont cheat but some chips top out quicker than others. And i do burn the chips in and run as high of a vcore as a particular core can allow b4 burning out.

[fivecheebs]

hehe!

It was a joke mate, since you replaced the CPU

[jaguarking11]

hehe!

LOL I get it. But the 530 toped out at 3.9ghz @ 1.6vcore. I even tried higher vcore to make up for the mild droop (1.65v) to hit 4ghz with my ram on divider and it still would not be stable over 3,9ghz.

Now with my 630 im stable at 4ghz @ 1.5v but the dfi mobo dosent like anything mutch over 267mhz even though I maxed out the chipset voltage and I put an 80mm fan blowing on it. Now for my bit of bad luck. The pci-xpress card I ordered with my abit al8-v is completly dead. It was damaged during shiping. And the psu I ordered for my father was doa as well so I gave him my psu. so at the moment I dont I am using my litle sisters machine with my hdd in it. Its going to be a cuple of weeks untill I start experimenting with this 630. ANd Being that I have 2gigs of patriot ram im definitly going to love this new machine.

[fivecheebs]

Its always a bummer when stuff comes DOA or damaged. I hope you get a good RMA turnaround.

Well the videocard I was asking for a doa. It is a refurbed 6200 made by apollo. But the psu I was completly suprised. My friend has two of the same psu's and he has had them for about a year now and both are awsome.
