E8500 overclock problem on 945gcm-s2l

[filiprajcetic11]

Hi. I have a problem with my cpu e8500 whitch should be working on 1333 FSB speed. My motherboard max FSB speed is 1066 but it can support 1333 by overclocking. When i installed processor the motherboard downgraded speed to 2.4 ghz without overclocking. I tried to overclock it, but I managed only to 2.8 ghz. When i tried to go ever higher it just do back to 2.53 Ghz. In bios i also have option to automatic made 1333 FSB speed but when i save that and restart computer it just go back to 2.53 ghz. I am not expert in overclocking and maybe im doing something wrong. I really dont know. A help would be appreciated.

That CPU is supported with BIOS version is F6 or newer. What version is your BIOS?

 

[filiprajcetic11]

My bios version is f8d. That is the lastest version

Did you try resetting the BIOS to the default settings?

No i didnt i will try that now

I did it. After i did that i tried to set the o.c 1333 duo core option in bios but after restart it went back to 2.53ghz. I didnt try to manually set speed but i think that wouldnt work either.

 

[filiprajcetic11]

Can you tell me how to overclock. Maybe im doing something wrong there?

 

[GhislainG]

Why not make sure that it runs at the rated frequency before trying to overclock? Once you reset to the default values and save them (a very important step), you shouldn't have to change anything. It should run at its rated frequency in the BIOS.

After i reset bios it goes to 2.4 ghz. 1066 fsb

 

[GhislainG]

I now understand what you mean; you need to force the fsb to 1333 MHz to get the CPU running at its rated 3.16GHz frequency.

You enable "O.C FSB1333 Core 2 CPU" and set "CPU Host Frequency" to 333 MHz?

Yes and after that pc just restarts for 2-3 times and goes back to 2.53 Ghz

There isn't much else that you can do. The motherboard, released 10 years ago, certainly is no longer under warranty. If you absolutely want to use the E8500 then consider a used motherboard that fully supports it without overclocking.

Somehow i made it. Now its working on 3.16 Ghz. I changed voltage from 2.25 to 2.3 and now i have ram on 500 Mhz. Is that ok? Becouse max ram speed for my board is 667. I have option to multiple to 1.5(500Mhz) 2.0 (677Mhz) and 2.5(800 Mhz) and auto. But it only work on 500 Mhz.

 

[GhislainG]

The manual mentions what RAM frequency is required for 1333 MHz. What modules do you have and how fast do they run according to CPU-Z?

 

[filiprajcetic11]

Ok here.
DRAM Frequency: 250Mhz
FSBRAM 4:3
Slot 1: 2048 MBytes
Frequency: JEDEC #1-266Mhz, JEDEC #2-333Mhz, JEDEC #3-400Mhz
Slot 2: 2048 MBytes
Frequency: JEDEC #1-200Mhz, JEDEC#2-266Mhz, JEDEC#3-400Mhz.
I dont know is this what you asked for. Also its important to say that i have 4 gb ram but only 3.25 usable. But i think that is another problem.

 

[GhislainG]

There's no manufacturer and part number for those modules? The different modules that you use probably prevent running them faster when the CPU is overclocked; I'd test at a frequency closer to 400 MHz using only one module to determine which one may cause issues. You'll never get close to 4 GB usable with a motherboard limited to 4 GB total.

I have manifacturer on 1 ram stick (Nanya Technology). I dont have reall problems. Also when i try to enable O.C for dual core option in bios it brings memory to 400 Mhz. .But because that option did not work(it just go back to 2.53 Ghz), I had to do the manual oveclock and its stable only on 500 Mhz. I dont have crashes and everithing is working fine. Im even playing gta 5 lol. If i must change the ram to work on 667 Mhz i will do it, but if its not necessary i will leave it like this.

 

[GhislainG]

I wouldn't bother changing the RAM; the performance improvement isn't worth it.

Well now i have different problem. Every time i plug in my camera it shows up as floppy disk??

Unless the issue occurs when not overclocking, reinstall the drivers.

Ok thanks man.

 

[filiprajcetic11]

Ok... Hi again. After month of gaming something happened. All of the suden i have high temps 68-70 °C with no usage at all. Also 100% cpu usage. Is my cpu dead? Also in bios it shows temp of 43 °C but on every program on windows 68°C?? I tried to downclock on 2.53. Also cpu vent speed at max.

 

[GhislainG]

Did you check in Task Manager what process is using the CPU? 43°C in the BIOS is not abnormal, but 68-70°C in Windows with less than 10% CPU activity isn't. I've never see idle temperatures higher than they are in the BIOS. What cooler and is it installed properly?
