Can't overclock no mo'

[twilyth]

One of my quads was oc'd to 3.6ghz and has been running fine at that speed for months. Today I noticed that it was hanging and had to reset. When it rebooted, it went back to default settings. I tried oc'ing several times to lower speeds down to 3.2ghz and could not even get it to boot - even with voltage bumped up to 1.5 and down to defaults. It would usually go to the bios screen and then reboot. Never got to Windows screen except at default settings.

Temps in bios for cpu were in the low 40's Celsius which I guess is high for idle speed but I haven't made any changes. However I will check fan/hs seating and thermal paste tomorrow.

The system is q01 in my sig.

Any ideas? It's running fine now at 2.4ghz and tomorrow I will try oc settings of 2.6 to 3.0 ghz to see if that works.

No clue here but thats scary..Mine has been at 3600 also on 1.4375v but not as long as yours..
Yes to temps,40's at idle is high..

[أشرف]

If it went back to default settings, then it is not stable.

What is your vDIMM for DDR2 1066?

[purecain]

sounds like its your ram to me.... memtest is your friend in this case....
chances of this being your cpu on those volts are slim to none...
i've had my q6600 at 3.6 for 8 months and i abuse it with maximum volts and 4gig+ regularly... they can take it... your memory on the other hand is far more vulnerable... what speeds and volts has your ram been getting???....

hope you get it sorted....

Thanks for the responses. I'm kind of burnt right now but tomorrow I'll make a detailed list of the settings I try and the ones that were stable previously.

But off the cuff, I think I had mem set to 1050 timings at default and voltage at +0.30. Not sure what the defaults are for my board.

[TheGoat Eater]

my GB P35-DS3R did that and took a lot of time to get it back to OC settings - I still don't know why

But off the cuff, I think I had mem set to 1050 timings at default and voltage at +0.30. Not sure what the defaults are for my board.

I think it is usually 1.8v ... correct me if I am wrong though as I hate those +0.20v types of settings for voltages on the GB boards:down:

[STEvil]

Yes, 1.8v is stock.

Twilight...... I had a P965 DS3 go like that on me. Seriously! It will ONLY work at 266FSB default now. Even '1' change on clockgen causes a freeze. Luckily its a Qx6700 so I have it at 266x12.

[vaio]

Yikes, hope my ds3 doesn't do that.........I'd lose over 1 ghz on my lil Ally :eek:

[twilyth]

I was in crisis management mode today, so didn't get much done. Hoping tomorrow will be better. On the bright side, i did manage to get the other q6600 up to 3.4ghz with high temps around 65 under load.

A quick thing to try, since you have more than one system, is to swap in the mem from the "good" machine, into the bad and find out if your clock comes back. I have lost ram in the ways described above. I also have seen a mobo refuse to clock decently anymore. It is a P5B deluxe. As to CPUs, I had a really Extra Special chip run for months at 3.6, have trouble, and now it runs stable at 3.5. I did not totally troubleshoot that system, past the RAM, since it's on a P5K. Too lazy right now...:p: The point here is that the CPU usually doesn't change as radically as you describe. It's "usually" something else that goes.

On the other hand, a dog CPU seems to be a dog CPU no matter what you do. I played plenty of musical CPUs to find that out. I own two, and they have all the other dog/used/nasty components around them. But you know, they contribute faithfully to my contribution everyday since I don't expect much out of them.....:ROTF:

RAM is the weak point for crunching, and I've lost a few sticks. Always good to have fresh spares if you've got several machines and the budget for it. DDT has reported the same on other threads here. In comparing farms to VietOZ, neither of us run our RAM higher than 2.1. If you do, you're asking for trouble. D9 chips are great for benching, but we've had more long term luck with promos!!

I actually like the 680i boards I run, for this reason. The mem is completely de-coupled from the processor speed. I drop my weak RAM in those boards and go with the strong stuff in the Gigabytes and Abit machines. (OT I know, sue me....anyone know anything about the new 780i boards?)

It works for me...your farm may differ....;)

Luck to you, let us know.

Actually Bob around here you are penalized if you stay "On Topic". :rofl: :rofl:

The thing I don't understand though, is if the ram is stable at a given frequency, then why does it matter whether or not the cpu is overclocked? I'm probably going to look stupid for asking this, and maybe I am, but if running the ram at 1066 with default cpu and ram multi's and fsb works, why does it choke when I set it to run at 980 with a higher fsb and lower ram multiplier? That makes sense if you've got a crappy memory controller, but then swapping out the mem won't make a difference - right?

I have only a cursory understanding of the m/b architecture to be honest.

What I can do is put in some ddr2-800 ram that i'm using for the new phenom rig and see what happens. Hate to take down a working cruncher, so I will take that advice about getting extra ram. A couple sticks of ddr2-1066 should be pretty cheap and i need to order some other odds and ends anyway - any excuse to order something newegg :rofl: :rofl: :rofl: I may as well see what another quad rig would cost, and maybe a 30" monitor, and a blu-ray recorder and . . .

I need an XSDC intervention - HELP!!!!

I also don't pretend to fully understand all the nuances of mem timing but I have seen sticks slowly fail even when they were clocked below rated speed....Weird. I think we are looking at a slight degradation of the Mem chip's timing performance. Enough to make it fail, perhaps in combination with a not-so-strong mobo mem controller.

On the other hand, I have some corsair 800 Mhz RAM with promos that has been bullet proof, no matter what machine I put it in. Luck of the draw, I guess.

Perhaps others can chime in here.

Dr SiG will likely set up an appointment for you if you ask....:rofl:

It sounds like you are perfectly normal to me though. If you have an extra fan laying around, that's the start of the next cruncher machine.....you have to acquire the rest of the parts, rather than let that fan sit idle.....:eek: :up: :ROTF:

Yes, I would have to agree, I hate my P35-DS3R (Rev 1.0) incredibly hard to get stable at 3.6 and Huge vDroop (.9 under load :shocked: ) Luckily spring break is coming and I'll be grabbing a P5K-Premium and try and hit 3.8+ for 24/7 :)

I had a DFI P965 board go like that on me. At least with the quad that had been running in there. Was at 9 x 400, and fairly loose mem timings. for like two months. And then one day, wouldn't run at a lick over 266 FSB. rediculous. Had to run it like that for a bit til I bought a P35 board and kicked the DFI to the curb.

In fact I'm on the that quad and the board I replaced the P965 DFI with right now.
( it is a P35-DS3R... running at least 4 of 'em )

Yep! QFT+1.

Robothead. Your really need to be listening to this. If in your testing the ram is not at fault, its likely that your getting the same as what me and Scott has seen with ours.

See the pic. If I use Easytune or clockgen to move that FSB either up OR down, she'll freeze. If I try boot any higher it won't work. The DDR800 ram is good. Have tried diff sticks anyway. Its just the board.

sorry to hijack this thread, but i was searching the internet and it looks im not the only one with this problem.

yes it happend to me aswell, and yes i have the ds3r mobo. i have an e8400 that used to clock at 4.2ghz 24/7 with 1066mhz ram ran at 1121mhz. i was happy with those settings. but my ballistix d9 memory crapped out on me (actually its my second kit of them). i was so mad about that and i didnt want to do a rma process because i hate those. so i went to the store and bought corsair xms2 800mhz i think they are promos. so yea it was the only thing i could get that was in stock. the memory was the bottleneck because i had to downclock to 4ghz. at those settings the memory was slightly overclock but they were not ran over 2.1v wich is what specs says anyways. i used this settings for few days but i got tired of this and i wanted my oc back. so yesterday night i wasnt abl;e to sleep so i got up and started overclocking again (yea it happens often to me). i pumped 2.4v to the ram and 4.5ghz to the cpu and started memtest. but i got errors after few minutes, so i said no problem i will go lower. now its where things started to go bad. i lowered to 4.2ghz wich is my usual 24/7 settings but it was rebooting after bios and revert back to stock settings. so i said ok im gonna boot back at 4ghz like i was able to do with the corsair memory and work my way up again. Nope! it was rebooting again. so i tried 3.5ghz. Nope! 3.2ghz. Nope! so well now it only wants to work at stock settings. i have tried every voltage, frequencies and dividers possible. i also have active cooling over the memory and they never get even a little warm, because i have cold air intake in my case. and my cpu never gets pass 60c on load and 30c on idle. so i let it at stock and ran orthos overnight while i was sleeping. this morning i woke up and i saw it was orthos stable for 5hours. i am now testing memory at stock settings with memtest.

so what i can do when i get back home from work is to test my working stick of ballistix remaining to see if that can rule out a memory possibility. if its memory related then i dont realy care i will go bhack buy some more. but im VERY scared that it could be my cpu or motherboard that are dying. i've been overclocking for years and years and this kind of thing never happend to me before. so im kinda clueless to what i have to do here.

specs:
p35 ds3r rev 1.0 with lastest bios
2ghz corsair xms2 pc6400c4
e8400
galaxy 8800gt 512mb
antec900 with winters cold air intake :D
corsair hx520w
segate 200gb sata
dvd burner

if anyone can help it would be realy appreciated thx
