Help OC 9950BE

post #1 of 15
Thread Starter 
What I'm trying to do is get my cpu to 3ghz and oc ram.

Monitor: Samsung P2570 70k:1 cr, 2ms

Mobo: M3A79-T DELUXE

CPU: PHENOM X4 9950BE 2.6ghz
-FAN: ZALMAN 9700NT

RAM: OCZ 2 X 2GB = 4gb total
DDR2 800MHZ
CL 5-4-4-15(CAS-TRCD-TRP-TRAS)
2.1 volts

PSU: OCZ 850W

GPU: EVGA 560 TI FPB - New upgrade

HDD: SEAGATE BARRICUDA 7200 32MB

CASE: NXZT APOLLO /W 2X ENERMAX MAGMA CASE FANS + 1 STOCK FAN








I'm confused here.

Memory set to DDR2 800 (is it 800 or 400?)
Reference clock = 200mhz
Multiplier = x15
200x15 = 3000mhz

Divider = 8

3000mhz / 8 = 375mhz (750mhz effective). What I want here is 400mhz and not pass it so I have to overclock Reference clock in order to get that?

So my memory is underclocked even when I haven't overclocked anything @ 742.84mhz effective

That's what I got from overclocking guide I read, only made it to section 2 before my head overloaded. I just need more help, ram is killing me!

Overclocking
---
So far this is what I learned today.

1. Reference clock (Bus speed) stays at 200 while I Change multiplier to 15 giving it 3ghz core speed and save settings. Without adjusting volt levels I should be good?

2.a. Overclock memory after overclocking cpu then save settings?
or
2.b. Go to windows (or safe mode) run a stress test (Prime95 - small ftt or blend) to find stability without overclocking memory? I'll do it as soon as I know more about it, learning it as we speak.

-Prime95, stress test...haven't downloaded it yet. Just want to know what to do first before I burn my computer down so I honestly don't know what small ftt is other than cpu stress test.

400Mhz RAM in CPU-Z is 800Mhz DDR
You'll want to get those timings down and voltage up to rated

So my timings are 6-6-6-18-20 on cpu-z, lowering it would make it faster? How low would I have to go, as listed?

Also for cpu, 1.25v and multiplier x15 for 3ghz is good or I need to up the voltage on that too?

Yes, the lower the timings, the lower the delay, the faster the chip reacts. Increasing timings increases the clock, but also increases the delays. So, your chips might appear to be operating faster, but a benchmark test may show otherwise.

Memory is a tricky overclock on some boards. You lower each timing individially then test the chips response. Sometimes, lowering timings may make the chip operate worse, but usually a voltage increase can help. It can be a very long and extensive process in order to find the right combination of MHz, Timings, and Voltage.

I have not researched your board and bios to see how much control you have in the bios. Can you set your memory clock manually and also change all of your timings manually? If you can set your memory speed, what kind of multipliers are available?


Take a breath.....

Your CPU, I would change your memory voltage and timings to factory specifications. I would then change your cpu multiplier to 15x. Boot and test it with Prime95 Small fft. If it fails, raise your voltage. Only raise your voltage in the smallest incriment allowed. (.125 or .25 or whatever your bios allows) Run Prime95 and repeat until you find a stable voltage.

You can usually tell if your going to fail at that voltage within the first 5 minutes. But, once you think you have the right voltage, you should then run Prime95 for at least and hour or longer to make sure your stable.

When you get that straightened out, play with your memory timings and voltage, but if you have not tested your cpu intensely, you might want to take it's settings back to factory defaults before you play with your memory.

Prime95 Blend tests a little of everything, but there are better torture tests for memory by itself. memtest is a good one. http://www.memtest.org

EDIT: Check on OCZ's site to see if CPU-Z is giving you the reccommended timings. I always check.

Is the ocz specs listed enough or too much? I honestly don't want it overclocked to the max, just a little. I want to keep the heat on the low, 2x intake 120mm and 1x 120mm exhaust case fan

I need help fast, I just put 2v and its showing up as 1.8v so I did something wrong. And same thing still shows up in SPD



My bios settings are all in auto, I'll take pictures of that too. I just hope I didn't do anything wrong. Memory shows up different though, trc is 12 and 1t from the previous picture above.

I loaded everything back to defaults at the exit page and now it shows up as this.



What should I do here? Enable\\Manual everything or leave it at auto and change those that actually need to be changed

Ugh
400Mhz with CL6!?
Way below rated of 800 CL5-4-4-15. You should get those set!
First set the speeds & voltage, then go to "DRAM timing configuration" and set up the other timings manually

You say change the speeds and voltage, FSB & DRAM Voltage I'm assuming.

What you need to change:
DDR Voltage - rated voltage of 2.1V
Memclock value - 800Mhz

2T mode - 2T
DRAM timing mode - both (you will have to set the timings twice but this makes sure the timings are applied to all DIMMs)
CAS Latency (CL): 5
tCWL: auto
tRCD: 4
tRP: 4
tRAS: 15
tWR: auto
tRFC values: lave them
tRC: 19 (raise this if unstable in OS)
tRRD: auto

Then run HyperPi 32M to make sure it works correctly.

As for OC-ing the 9950 BE, it's a black edition. Raise the multiplier. Raise voltage when needed. Only thing I'm not sure about is voltage limits with the 65nm Phenom chips.
