OC'd Celeron D having problems

[perdomot]

Hi everyone. I bought a Cel D and an Asus P4P800-E Deluxe mobo to duplicate the results I saw in the Xbitlabs article. I got it to 3.6 Ghz and tested it with Prime and Memtest and everything seemed great. Unfortunately, when I started trying to encode some video with TMPG, I ended up getting errors or the PC would reboot. I bought this combo specifically to encode video but it seems it doesn't want to do that. Any ideas what might be wrong? Thanks.

how long was p95 stable for?

try throttling your overclock back 200 mhz and see what it does

I ran it for about 6 hours. No problems with Prime or several loops of Memtest. Works great while surfing the web or listening to music but when I try to encode video, it reboots after a couple of minutes.

socket,
I don't want to throttle it back because I got this so I could OC and encode video faster than my 3200+ Barton rig. If I keep throttling it down, it wont be any better than the XP rig. One thing that I think might be part of the problem is the fluctuating Vcore. Seen this mentioned before but I can't do any soldering mods to fix it. Others seem to have gottent their rigs nice and steady at 3.6 Ghz although they don't mention if they encode video. That seems to be the main problem.

Yes you can, it's a drop mod. It will stable ALOT youre vcore output.

Are you sure the power supply is adequate?

Yeah, your overclock isn't stable, clock it back down.

Are you aware that Xbit used a Zalman 7000 on the CPU, DID YOU?

If you list your entire rig, keen eyes might see the root problem.

Stormgiant,
Let me rephrase that: I don't have the equipment for soldering and considering how small the points are, I'd rather not risk it.

Rouge1979,
PSU is an Antec True Power 430.

21sthermit,
Cel D 2.66
Asus P4P800-E Del
Geforce Ti200
TBSC sound card
2 Hitachi 7K250 HDDs
HP DVD 530i burner
Antec TruPower 430 PSU


I put a HS that goes up to a 3.2 P4 but replaced the fan with the Smart Fan from TT and left it on full so temps are not an issue.

From your equipment list no obvious flaws. Suggest you read this thread, should give you some insights into the problem. From my read, two things popped out: 1) FSB "Holes" and 2) Current BIOS. Your MB is the best, so if the BIOS is current, you should be flying.

Deleron 2.66GHz... you mean the 330? That needs to clock to 4.0GHz for 200MHz FSB (in BIOS, CPU will see 800). I have a Deleron 330 and 320 (2.4GHz). My 320 will go to 200MHz FSB easy, my 330 will not. My motherboard is an Asus P4P800 Deluxe (not newer "E" version). It does NOT like running between 160-199MHz FSB. If you are running your Deleron 330 at 3.6GHz then you are at 180MHz FSB, smack in the middle of the FSB "hole" present in my board. Even if your board doesn't have that problem (it may not) your CPU still may not like the speed.

BTW, what RAM are you running (type/configuration/latencies)?

I got a 320 as a temporary replacement so didn't seek out the latest stepping and happenend to get a C0. Without increasing voltage it does 170. 180 was no go and ditto 200 (which I figgered would be a quick "hole test". Game performance is almost equivalent to my previous P4 according to some casual 3DM01 results (actual game play is the same), so good value I reckon.

P2.4 @ 2.9 / R9700 4.60 / 15834
C2.4 @ 3.0 / R9700 4.12b / 15237

Well, I tried another Asus mobo and this one seems solid. Got the Cel D going at 3.6 Ghz no problems. Going to go for 4 Ghz tomorrow. Wish me luck.

let us know how that goes

 

[perdomot]

Well, looks like 3.6 is what I'm gonna get out of this chip as anything above 180 wont work. Not complaining though. At this speed, my video encoding has been cut down by 1/3 so I'm definately a happy camper.

Great News.

What are you comparing against? What video encode program? Which two systems?

 

[superkdogg]

Just like in my thread that was linked! Motherboards seem to be the limiting factor on Celly-D OC's. Now if somebody knows why, that would be helpful. Mine wouldn't go over 2.8-9 on my 865PE board, but does 3.6 @ stock vCore in my wife's SiS motherboard with no problem. Weird.

 

[perdomot]

I used TMPEG to encode to MPEG2 and my old rig took 1hr 37min to encode a ripped DVD but the new rig did it in 61 minutes. Very nice gain.

superkdogg,
Try raising the vcore to 1.475 and vdimm to 2.75
