Need some Help Overclocking a OEM system that uses FSB HT Bus.

I have a Aspire X1301 System.
http://reviews.cnet.com/desktops/acer-aspire-x1301-u130...

I'm using Nvida System Tools.

Computer Specs
AMD Athlon II X2 215 (Dual Core 2.7Ghz),
Transcend Information PC2-6400 (400hmz) 2gb x2 http://oi41.tinypic.com/2zdt4de.jpg
Upgraded
Bigger Case
3tb Sata
350W PSU (Was a 220w)
Radeon HD 7750 OC.
http://oi42.tinypic.com/2zz6wlx.jpg CPU-Z
http://oi39.tinypic.com/qrkqdy.jpg 20mins in Prime

I overclocked the 200Mhz HT Bus to 252Mhz giving my CPU 3.4 GHZ and the Ram to 506Mhz.
I ran Prime95 for about a hour with no issues at all. The heat only raised 5c.

http://oi43.tinypic.com/2emijxy.jpg 45mins in Prime.

It seems like the CPU can take being overclocked that high. I'm worried about the Ram going form 400Mhz to 506Mhz. I can't seem to find away to bring it back down to stock. If Prime95 Ran for a hour with no issues at all (I even ran a game at the same time once) does that mean my ram and CPU is stable enough to use with no issues? I just don't want to blow up my ram or cpu.

Best solution

You are likely as high as you are going to get on an OEM MB. If your CPU and memory are running stable at this freq, then you should be good to go. If you are running the stock CPU cooler I recommend changing it to one that can remove more heat, other than that you should be ok.

I've been running Prime95 since 3pm. My Cpu temp has dropped to 40 and the Mobo 50. It was running 43 for cpu and 58 for mobo. This is on a stock fan. I'm no where near the temp being high. I may still upgrade the fan just in case. I've had no errors or freeze ups at all.

If your temps are good on stock cooler than it should be ok. you stated that temps went down 3 and 8 you need to check and see if the CPU is throttling itself due to heat. Although it is not unheard of for temps to go down it is not common do you have a multi speed fan? Run CPUZ and ensure the clock speed in not being reduced.

Nope still full speed. Yes, I have a smart fan that speeds up and slows down when needed. Same with my graphics card.

Good!! This really should help with BF3. 64players is unplayable online with the dual core 2.7Ghz. Should run a lot better at 3.4Ghz. Tested it lastnight. Was staying above 30fps when I was getting 19-22.


It's been 12hrs still no issues at all. CPU 41c Mobo 56c Fan Speed 2100rpm normally runs 1600rpm

That is normal CPUz is correct.

I've never overclocked before. What should I use in my power opinions on Windows 8? High Predominance settings?


This is what I got with prime after 24hrs...http://oi44.tinypic.com/qqz6z7.jpg No issues at all.

Based on current system stability I would continue to use whatever settings you were using before. Typically high performance with sleep enabled.

Thanks!!! Thinking of seeing how far I can push it and keep it stable.... GPUboss says AMD A x2 215 can be overclocked to right number 4Ghz but I would need to upgrade my fan. Even if I was 10-25c under temp.

You will likely start running into memory frequency issues. Also does your board support changing the CPU voltage? You will likely need to start upping CPU voltage to go much higher and if your board does not support increased voltages then you will start having stability issues.

I'm not sure. Ill just leave it were it is.

I've been reading up on Overclocking on forums. Some people said you need to decrease HT Multiplier to keep the HT Bus Frequency near the stock 1800Mhz. When I OC the HT Bus Frequency went up to 2277Mhz. Computer was stable after a 24hr prime test.

Can this hurt anything?
Do I need to lower the multiplier?
Will I lose any power or anything?

If you have the board has the ability to lower it then yes lower it if does not then leave it as it is.

Yeah I can lower the HT Multiplier... Would I need to do another 24hr stably test?

HT Bus Freq
x7 1771Mhz
x8 2027Mhz
What would be better? A little under or over?

A little over would be faster, and should be fine. No real need to do another test.

Can't go a little over... It would be 227Mhz over. Would that be ok? The 1771 is only 9mhz less.

Just had something strange just happen to me. I don't know what it was.
I was playing around with AMD CCC turned on Windows Scheme. The CCC icon went away so I tried to force the CCC back on so I could turn it off. Everytime I would force it back on my screen would flash and my background would become white and the start bar looked like the old ones than it would go back to normal with no AMD CCC pulling up.

So I restarted the computer. In post I got the normal one beep telling me the system is good to go. About 4seconds into the windows 8 loading a 1.5sec beep happened. About 4seconds later Windows 8 login screen was up. Temps normal, everything working like normal. Fixed the CCC problem rebooted the computer loaded normal. Rebooted again, shutdown for about 20seconds no beep again (But for start up beep).

I don't get if CCC screwed something up or if something is wrong.




Side Note: It's amazing how fast windows 8 boots. Goes from system totally off to Windows 8 Lock Screen in about 12seconds. Takes longer for the Acer and Bio's Info to go away.

You are running on an OEM stock motherboard here, leave good enough along as it was running well with the overclock you had on it.

If you are interested in seeing how much a new motherboard/cpu/ram will cost you if yours fail due to attempts to get 5% better game speeds, you are heading in the right direction.

"Hey, the turbo in my car can go to 10psi when it's only 7 on stock, whee, more speed. Hm.. if it can do 10, it should do 11. Whee more speed. Well if it can do 11 why not 12?? Oh look, a flying cylinder though the hood, wonder how much a new engine is..."

Yeah I'm not missing with it anymore. Got 26.6% overclock with stable system no issues at all. I don't see a point in overclocking it another 0.1-0.2 Ghz more.

Only thing I did was drop the Multiplayer so I could get the HT Bus freq back around stock speeds. Not sure what could happen since the system is stable with the HT Bus freq at 427Mhz over the stock but I don't want to risk it so now I drop it 9Mhz understock.
