The truth is I have never been a fan in overclocking but yesterday I said to myself "hey what can I lose for trying to get a little more performance of my CPU after all is an AMD ;) and everyone seems to do it without any problems at all. " So I decided to give it a try, to make the story short I was out of luck :(, I even got a message after I put all the settings back to normal saying that "some registry files were recover from a log" (something like that) Anyway I manage to get the processor running at 2.6ghz but it was not stable and I don't know why and thats what I would like anyone could help me out with. What exactly configuration I need to make in the BIOS to make the overclock stable. (sorry for the long post :o ) Thnx in advance sincerely: --Phanto Posted by: coleman not a pro at over-clocking at all, but over-clocking with a stock fan is a bad idea in all. The reason why you are probably getting an error message is because the temperature of your CPU is rising and you BIOS is picking it up and seeing your CPU temp as unstable. Getting a new Heatsink/Fan for your CPU will reduce the temperature of your CPU by approx. 10 degrees, this gives you a lot of room to over-clock while keeping your CPU at a stable temperature :) now this is just a guess, and i would like someone to back me up on this :p Posted by: nitestick you can overclock as far as it will go!!! there are two probable causes for your instability 1. the cpu needs more voltage (Vcore) 2. the memory is unstable from being overclocked with the FSB. "loosen" the timings, use a divider or increase the memory voltage (Vdimm). i don't reccomend messing around with the voltages of either too much. voltage is the main thing that CAN fry components if you're not careful or don't know what you are doing. if you have voltage adjustments available to you only ever increase by the smallest possible increment, stability test and then if necessary try a little more. you should always be aware of the voltage limits for your components though as exceeding them could cause damage. for your processor i would be confident giving it 1.4v in any situation as it should be warrantied for that.

[/B][/QUOTE] what u have to mess with the voltage to OC? Omg, i didnt know that n BIOS always told me to not set it too high or i damage the RAM, or in this case, the CPU. Get's me scared to mess with the voltage :amazed:.

[/B][/QUOTE] When I tried I did lower down the HT Multiplier to 3x the Memory speed to 133, then 166 and the last time I just let the stock speed 400. (BTW when I left the DDR running at 400 it was actually running around 420mhz. If I remember correct the first time I tried to overclocking the PC manage to boot fine but when I was downloading some benchmark programs e.c.t suddenly the computer stop responding and freezes and I did have to press the hard reset button. In the second try I manage to change some setting in the BIOS and then run PC Mark 05 but before finishing the tests the PC restart itself. So what should I do? Thnx in advance once again :) Posted by: Phanto Update: I manage to overclock the CPU doing the exact same things as the last time only this time I did what nitesick told I increase the memory voltage to 1.4 and so far I run the PC Mark 05 and went up from 5191(stock) to 5661 (2.6ghz). I will be running the Prime 95, and let you guys know if something comes up. Thnx all for your help :D Posted by: nagasama great. yeah reading your post, when it freezes or resets itself, it is usually the cpu voltage. note the word ususally. i know that when i have a ram issue, i will get a bsod...not a freeze. do you still have your ram running at 400mhz? i would definitely leave the cpu multi at 4. it will cause instability (highly likely) if you leave it at 5. also, i suggest lowering your ram speed to the next lowest or two settings below 400 speed (keep it below 400) and push the cpu as far as you can. then, if it is stable, try to up your ram speed to either get it close to 400 or overclock it a little (always nice lol). if you get past cpu ext clock of 250, you should lower your ht multi to 3 (you want to keep it at or below 1000 for stability reasons). p.s. i think you mis-typed...? you said you raised memory voltage to 1.4, i think you mean cpu voltage. you should monitor your temps while running p95 and that will give you a good indication of your cpu max ok voltage. i personally don't like to see mine much over 60 running p95. unless you are doing some intense work on it, you will hardly ever use as much resource as p95. i can juice mine up to 1.6V and still be at a relatively comfortable temp, but the performance trade off is not worth the heat generation in my opinion. good luck! Posted by: Pepsiboy700 Hey Phanto, I have the same board as you sadly but it has a bfg sticker on it. The bios should be similar and if thats true overclocking will be tough. I wish I had a DFI right now instead of this POS (Thanks Mom!). Posted by: Phanto Update: When I arrived from the gym today at 7:00pm I stop the Prime95 stress test after 6 hours & 43 minutes with 0 errors, 0 warnings. Yeah!! Posted by: nagasama seven hours satifies my requirements of stability when i overclock... now go up farther lol Posted by: Phanto [QUOTE][i]Originally posted by nagasama [/i] [B]great. yeah reading your post, when it freezes or resets itself, it is usually the cpu voltage. note the word ususally. i know that when i have a ram issue, i will get a bsod...not a freeze. do you still have your ram running at 400mhz? i would definitely leave the cpu multi at 4. it will cause instability (highly likely) if you leave it at 5. also, i suggest lowering your ram speed to the next lowest or two settings below 400 speed (keep it below 400) and push the cpu as far as you can. then, if it is stable, try to up your ram speed to either get it close to 400 or overclock it a little (always nice lol). if you get past cpu ext clock of 250, you should lower your ht multi to 3 (you want to keep it at or below 1000 for stability reasons). p.s. i think you mis-typed...? you said you raised memory voltage to 1.4, i think you mean cpu voltage. you should monitor your temps while running p95 and that will give you a good indication of your cpu max ok voltage. i personally don't like to see mine much over 60 running p95. unless you are doing some intense work on it, you will hardly ever use as much resource as p95. i can juice mine up to 1.6V and still be at a relatively comfortable temp, but the performance trade off is not worth the heat generation in my opinion. good luck! [/B][/QUOTE] Yes before I went out I remembered that I made some mistake in the post it was actually the CPU voltage that I change to 1.4 also the cpu ext clock is around 220mhz and the memory is currently running at 440mhz. Posted by: Phanto [QUOTE][i]Originally posted by nagasama [/i] [B]seven hours satisfies my requirements of stability when i overclock... now go up farther lol [/B][/QUOTE] I don't know about that I remember I read somewhere that I should not overclock more than that if I was with stock cooling. But now that you mention "go farther" I'm thinking on overclocking the VGA I have been able to get as far as 420mhz once from 350 stock but last time when I tried Id get some bizarre graphical color in games ( CoD2 for example) trees purple and pink lol the worst part ?? I jsut tried to raise the core to 370 and still get does bizzare colors issues. Posted by: Pepsiboy700 Your bizzare color issues is the video card artifacting because it is unstable. You should downclock and scan for artifacts till its stable or set it to default and slowly work your way up raising it in 5 mhz intervals and run a artifact scanner like atitool for 10 minutes. Posted by: mlr i managed to get mine running at 2.76 ghz ,230 x 12 htt 4x vcore 142 ram 2.80 with no isues ran prime 95 for 14 hours i just bought zalman 9700 flower cooler which keeps ,my temps at 33c, - 40 too 45 under load Posted by: WWS I was able to overclock my X2 4800+ to 2.82GHz and that is about all. FSB = 332 CPU Mult = 8.5 Mem = 133 Vcore = 1.6V VDimm = 2.8V Mem Settings are 2-3-2-6 Posted by: mlr vcore at 1.6 volt how long have you had it that high i was a bit nervous about going as high as 142,what are yer temps here are some crazy overclocks with the 4800 [url]http://www.ripping.org/database.php?cpuid=46[/url] Posted by: Phanto Last Update: Yesteday before I was going to bed I start watching a video of the GDC keynote of Sony e.c.t streaming from gamespot website while watching the video I got a Blue Screen of Death, to make the story short yesterday before i get to bed my pc have 3 to 4 Blue Screen of Death (BSoD) in 1 hour, I couldn't help it and just put back the stock CPU clocks and everything start running fine again I don't know why the cause was but can anyone tell me what I did wrong while overclocking :( ? I even download and install a program before reverting back to the stock settings, a monitoring program for several parts of the hardware including the CPU and was running at 33c vBulletin Copyright ©2000 - 2003, Jelsoft Enterprises Limited.
