E8500 and GA-EP45-UD3P overclock help

[mattnova]

mult is at 9.5 and host freq is at 266 yielding 2.52 gHz, which is way underpowered for what it says it is (3.16)

[WilliamP]

Please answer my question about the Memory settings.

[mattnova]

o man i totally misread your question. unfortunately i am at work and cannot remember what the memory setting are.

[WilliamP]

The reason this is important ,is when you increase the CPU Host Frequency, it will also raise the Memory Frequency. This is what caused me problems to start with. So, if right now your memory Frequency is 800,and you raise the CPU Host Frequency then the memory frequency will go too high. You would have to lower the System Memory Multiplier first.

[mattnova]

i see what youre saying. so if the memory freq passes what it is rated for, then dial back the multiplier and just increase the FSB?

[WilliamP]

Look at it this way

CPU Clock Ratio 9.5

CPU Host Freq. 350

Equals 3.325 CPU Frequency

 

CPU Host frequency 350

System Memory Mult. 2.28

Equals 800 Memory Frequency

[WilliamP]

To begin with I didn't realize this an it would shut down because I was inadvertently pushing the Mem. Freq. too high.

[mattnova]

so the system memory and and cpu share the same host freq but have separate multipliers?

[WilliamP]

That is correct.

[mattnova]

william if youre still out there:

 

this is what im set at right now.

 

This is my BIOS set up

CPU Clock 9x

Fine CPU Clock .5

CPU Host Clock Control ( Enabled )

CPU Host Frequency 375

PCI Express Frequency( 100mHz )

C.I.A. 2 (Disabled )

DRAM

Performance Enhance (Standard)

Extreme Memory Profile (Disabled)

(G) MCH Frequency Latch (400mHz)

System Memory Multiplier 2.0D

Memory Frequency (MCz) 800 876

DRAM Timing

5

5

5

18

 

 

now in the mem frequency line is says: "800 876" is the 800 what the memories standard clock is and the 876 the current clock?

 

i have the proc overclocked to 3.56 gHz atm and the ram at 876 mHz (what i believe) and ran prime 95 for 19 hours with no errors.

 

what do yall make of this?

[WilliamP]

Like I said to begin with, I'm not real smart at this. I would think that with you running the CPU Host Frequency at 375 and the System Memory Multiplier at 2.0D your Memory Frequency should be 750. Are you sure about those figures?
