Pentium D 820 overclocking?

[Trader05]

I recently built a Pentium D machine, got the combo from Fry's with an ECS Board and purchased Corsair DDR2 5400. I started tweaking my machine last night, set the ddr back to 533 from 667 and started to bump up the fsb. I tried 210, 215, 220, and then went to 233.

Now running at 3261 w/1.28v according to Cpu-Z, ran Sp2004 on both cores for 10+ hours, 70c on full load, 45.5c on idle. I'm gonna see how far i can get it up to more tonight. I was just wondering what other people got these chips up to?

Have you checked using S&M to see if its throttleing ? at 70c, it probably is.

Mine 3.43 ghz @1.475vcore 55c load both cores. Big typhoon to cool. I got to 3.6, but it throttles badly at that speed.

What do you use your box for ? The 3800 X2 combo at Frys for $349 would have been much better. I got this one just to play with, as I already have 4 X2 boxes.

Mostly encoding recoding videos and music, i gotta check that throttling

 

[Markfw]

Use S&M, and its almost allways core1, core 0 is OK, and throttlewatch doesn;t show the problem.

I have a Dell 9100 w/ D 2.8s, but don't know if you can o/c it. In any case, it makes a great space heater

 

[AkumaX]

heater! heater!

820D @ 3.15ghz, back down to 2.8ghz

At 70c, you are almost guranteed to be throttling, I haven't overclocked my 830 yet, having enough trouble with it at stock.

My 830 hits 3.8 easy with a slight vCore bump. And i just figured out how to heat my house this winter - LOL.

At full load, it host 80c - LOL. Just got the Big Typhon hoping to drop the temps a bit.

Also, I shut down the throttling feature - sweet - more heat.

Yea 830's are the shiz.
On ocforums {PMS}fishey got his 830@5555mhz!
Thats on LN2 though. (liquid nitro)

Shutting off the throttling feature in BIOS, doesn't actualy stop the CPU from throttling just so you know..at 80c you are guranteed to be throttling even if you were at stock..

Yes, you can't shut it down. Run S&M, as even throttlewatch doesn't even catch it. And when you do, look at core 1. Core0 looks normal, all the throttling is in core 1 to fool the throttlewatch software (IMO). Even at 3.8, by X2 3800@2550 will crush it, I know I did the benchmarks since I have them both.

And I guarantee at 80c it is throttleing. You can;t stop the sun from producing heat.

 

[AkumaX]

haha i wonder when i passive ran my 820D @ 85c what speed it throttled to :evil:

 

[Duvie]

Actually keep in mind that throttling on the P-Ds and P4s in general has more to do with the vcor set then anything...70c at 1.28v may actually not throttle or do it very very slightly....

When I start3ed raising the vcore the throttle point would drop...I think it was like 3c for every .05v...I actually got it to throtle at 58c with only a 10% or less vcore boost...

Lucky you, my poor MSI 945G Neo-F won't let me run FSB past 206 without not letting me turn it on (and the temp is just 39C).

 

[Cooler]

I added another fan to my case Today and got my CPU down exta 5C Now its 65C load.
I was able to hit 4.0 but i ran into so stablity issues so backed it down to 3.8 . (Its air cooled and no volt mod)

 

[Guga]

if you can cool it enough you will get great ocs.
I was able to boot at 4480 (320 fsb), with 1.55v but I'm frying the cpu and it is far away from stable.

At 4.2ghz@1.5v I can play games, and do almost everything, but crashes in superpi in less than a minute.

at 4ghz is rock solid.

Its on watercool

 

[Markfw]

why spend hundreds on watercooling ? I got my $322 X2 on a $30 XP90, and it does 2550, equive of a ~4.4 or better 820D per my own benchmarks !

Well.. perhaps because it gives me fun doing that, and because it was a lot quieter, and because I want to..

Are enough reasons??

 

[Guga]

and by the way.
watercooling systems are very cheap these days.
I spent less than $200 wi th mine, and includes cpu and gpu block, water pump and a 3x120 external radiator.

Even the cheapest X2 cost at least $100 more than the 820D.

Price/performance/overclockability to me the 820D is great.

 

[StratusSS]

my 820D is running at 3.56 ghz and gets to just about 68 degrees at both core load.
using stock cooler and volts
waiting for my WC stuff to come in

 

[DarkKnight69]

840 hit 3.8 No problem on AC Freezer 7 Pro. Idle in the 40area and full load is around 60degrees. Primestable 2 instances for 24 hours.

 

[stevty2889]

My 920 was chugging along nicely at 3.7 until one of the cores decided to die

 

[eno]

Does this sound right.

Asus P5LD2 board
-266FSBx4
-667mhz memory clock
Intel D 820 @ 3.74ghz / 1.425vcore in BIOS (CPU-Z shows 1.392vcore)

TEMPS Idealing @ 37c Tornado at 7v
Case 31c

Load runs no higher then 45c when the room is warm with Tornado at full speed 4800rpm.

Running a XP90c w/ 92mm Tornado modded with a extra 92x25 hollowed out bracket to space the fan a little further from the heatsink.

Hmm for some reason i want to get a 820 to see how it runs, i donno why :S
Any mainboards which support dual cores and ddr1 memory and AGP lol.
I think i will try to sell my single core 3200+ and maybe get on of these heaters for my second machine.

It makes no sense to get anything from the 8xx series now that the 9xx series is out. There are actualy more motherboards compatible with the 9xx series than there are with the 8xx, even some older 865 chipset motherboards.
