Got my X2 4800 in and installed, asking for some tips and pointers

[kman79]

Hey guys, I finally got my X2 4800 and installed it last night. I installed my new Thermalright SL-120 with a 120mm Panaflo fan, now the computer is much quieter than it was with the XP90 w/delta fan.

Anyways, after the complete install, I made the checks to make sure windows was good to go with the Dual Core, Hotfix patch was installed good, and dual core optimizer was installed also, along with the driver.

Started to OC. I knew from previous CPU that my Ballistix RAM was good to DDR500 and actually a little higher. So I tried Running the FSB @ 250 and multiplier at 12 @ 1.4V. Everything booted up fine and it even started running SP2004 Orthos fine but locked up about 5 Minutes into it. So I decided to go for more of a conservative OC and aimed for 2.7Ghz +/- 5mhz. Stressed it with FSB set at 245 and multiplier at 11 @ 1.4V, and it ran like that for 11 hours without errors. I shut the comp down and headed to work where I'm at right now.

Now my question is, if I wanted to run at 2.7Ghz, would I gain anything by running at a higher multi with a lower FSB? Also what is the max VCORE I should go to, and what is a good max temp? At the current config, idle temp is 31C and full load for 11 Hours CPU temp was at 48C.

Systems Specs are on my Sig, if anyone has any reccomendations or advice, please feel free to chime in. Any help is greatly appeciated

For the A64/X2 line, speed is king. You gain nothing running at 11x245 (2.7Ghz) if you run that same speed with a lower muliplier and higher FSB.

Your temperatures are excellent. Most give 1.45v as the upper limit of voltage, and as long as your max load temps stay below 55C, you'll be fine.

Wow, the fact that you could boot up and run 5mins of Orthos at 12x250 at 1.4v indicates you have a really nice 4800+, and you still have plenty of temp headroom. I would try something like 12x240=2880 at 1.45v

Thanks for the replies guys.

I'll up the voltage to max 1.45v when I get home tomorrow and see what I can get out of it. So basically as a rule, I shouldn't go higher than 1.45v Vcore and keep temps below 55C?

Actually, using the "max vcore of 110%" rule that we overclockers have been using since the first motherboard that would allow higher vcore, anything up to 1.485v would be fine. Quite a few people have been running @ 1.50v, since that's actually closer to 1.485v than 1.45v. It's all up to you, as to how much vcore you want to give it, since it was your money that bought it. But 1.45v is definitely safe. And I agree with guitardaddy, I'd shoot for 12x235-240.

Hey there,
Great to hear about your X2-4800. I have been running mine in my DFI Lanparty SLI Expert now for a few months. Run it at 2700 (so 12x225). The voltage I don't exactly remember now but it's around 1.37-- in fact it's just simply one notch up from stock. I get the EXACT same temps you do, using core temp which are roughly 29-31c at idle and it goes up to 48 at max if I let it run ORthos.

Honestly one of the best chips I have ever owned. Stable for hours (went like 10 then stopped). My only problem is the fact that my CRAP OCZ RAM (performance series) must be kept at 212Mhz or lower or it simly gives me errors. Hence I cannot run 1:1 but actually underclocking it now.

Your system seems to truly run well -- glad to hear it. I am using the big Typhoon by the way for cooling and running it at full speed which is still, in my books, silent. It seems that the temps are actually getting better with time, as the AC5 settles.

I have never tried going higer btw... always worried the volatge was too high as it is but heck if folks are doind 1.45+ I might try for 2900 if I get lucky LOL>

Hey guys, just to keep those interested updated.

Work has been hectic the last few days so I haven't gotten much tweaking done. But I did come home from work the other day, and played with it a little. I took everyone's advice is went for 2.8+Ghz, set FSB to 235 and Multi to 12 and Vcore set a notch down from 1.45. Posted and Booted into windows just fine, but errored out of Orthos within 10 minutes. Upped the Vcore to 1.45V and tried again. Started runing two instances of orthose and set affinity for each core. Only meant to run it for 15-20 Minutes, but fell asleep. Woke up a little over 8 hour later and jumped off the bed thinking that I fried my new Toledo, moved the mouse and was surprised that Orthos was still runing, so I stopped it. No errors running at 2820Mhz for over 8 hours, I was amazed. Unfortunately, the temp was too high for my personal preference at 53C. I know it's within the thermal limits, but I'd feel better running below 50C. Woke up a little early today and was just curious how stable it really was so I Looped 3D Mark05 for an hour. In that hour Max CPU temp was only at 45C, I thought that was pretty cool.

Just using the comp for what I normally do, I doubt I would ever use it at 100% load on both cores, so I don't see it seeing the 50C+ temps much if not at all with regular use. Just before I left for work this evening, I set it back down to 2.7Ghz @ a notch down below 1.4V and started running orthos again. It'll be more than 12 hours before I get out of work to see if it'll run below 1.4V at 2.7Ghz.

Appreciate the help everyone. I really don't think I need to spend that 953.99 for the new Conroe, motherboard and RAM. This was 280.00 well spent.
