Unable to overclock e4300 / Biostar 965?

Hello,
The last system I overclocked was Socket A, being a bit rusty I really need some help with this one. :D

My setup:
E4300 w/ Stock HSF
Biostar TForce 965PT
1GB (2x512MB) Corsair VS DDR2 667
PCI-e locked at 100MHz, PCI at 33MHz
-
The problem:

From what I read the multiplier for the e4300 was 9x. However, when I run CPU-Z it is showing up as 6x multi (every once in awhile it will jump to 9x then back down). My RAM is showing up as 333 with DRAM 3:5.

The max I can do is 260 x 6x @ 1.325v CPU, 1.8v Memory (2.35GHz)

Anything else does one of two things.

1. Blank screen and two long beeps.
2. Hard reset and then comes up that BIOS was reset due to overclock.

Attached pictures below.

Temps look good, never over 32* at full load.

Any help would be greatly appreciated, thanks!

Answered my first question after researching here and google. I did run into another block now.

It seems I cannot go past the 2.55GHz (282x9 @ 1.325v) mark. To be safe the memory timings are set at 5-5-5-15 and at 2.1v.

Unless they're wrong, based on the reviews of people with the Biostar board, higher clocks are possible with the E4300.

Any ideas? :confused:
 
Turn off speed step and give the ram 2.2V to try it out. The CPU does NOT need any more voltage at such low speeds.
 
SpeedStep is the problem to your first question about the multi in CPU-Z. I had the same issue. Disable it in the BIOS.

Next your running into walls because your ram is running over the top of your CPU. See HERE to help you out with the RAM divider. Your best bet is to run it at 1:1 since you have DDR2 667 memory and according to your CPU-Z shot your already running it at this speed. If you drop to a 1:1 divider it will be running at DDR2 564 instead (282FSB*2).
 
Thanks for the replies. I have tried finding the place to change the divider in BIOS, but can't seem to find it. Where exactly would this be listed under? I went through the motherboard manual, but it of course doesn't give much help.
 
Tried using the "Auto" option for the DRAM instead of 533MHz, but still the same results. I turned off speed step off so it's now showing 9X in cpu-z.
 
try bumping the vcore to about 1.35, then 1.37, then 1.40-ish. then crank up the fsb to about 300 and slowly go up. memory should be kept at 2.1v until you're sure that your memory is whats keeping everything low.
 
Update... With everyone's help it seems that the problem was 2 fold, primarily with my BIOS. The memory divider could not be set to 1:1 with the BIOS from Biostar and my memory topped out at 700MHz.

Flashed it to the 119 betabios from Rebel Heaven, vcore at 1.424, memory at 2.1v, 350x9, memory at 400 with 5-5-5-15 timing. Will run tests overnight, but seems stable at 3.15GHz. :D I don't think the memory will let me go further because it will not boot if I raise it above 350.

By the way, should I try tighting the timings or leave well enough alone?

Thanks for the help!
 
I spent an entire weekend working on this problem and finally figured it out....



I bought a different motherboard

Are you on stock cooling or something else? Right now I have made it to 3150MHz, 1.425vcore, idle is 23*C and full load after 3 hours of Orthos is 62*C?

Does that sound right or running too hot?

Thats sounds right for stock cooling


I'm running an XP120

Gah! I dont get how you guys have 1.4vcores at 1.15 on stock cooling. I cant go above 2800 at 1.225v on stock cooling, even that gets around 65C! Luckily my Aero Freezer 7 Pro is coming this week.
 
The ambient temps are fairly cool in the room where I have the system, should be interesting to see what happens this summer. I'm also running two 120mm fans that came with my Thermaltake Soprano case. Quiet and cool. ;)
