Quick overclocking with my new system

[dolphumous]

Check this picture:


All I did was loosen up the timing of my ram (Corsair TwinX3200XLPro) 2.5/3/3/6 and up it to 2.8V

Couple questions.

1. Why do all three show a different VCore?
2: nVidia Monitor shows 2 CPU voltages...difference?
2. I thought my HTT was higher before the OC...but I'm still 1:1 though. ?
3. What's the highest anyone has gotten thier TCCD and how loose did you have to get?
4. How the hell do I change VCore on an Ultra-D?
5. What's a VDD?

EDIT: Typo with RAM voltage

 

[dolphumous]

bump?

If I believe so, that is TCCD RAM?

If so, you can lower the voltage to 2.7, those timings are also a bit too high for only 235 FSB. You can try 2-3-3-6 @ 2.75

5. What's a VDD?

1. Speedfan and CPU-Z show pretty much the same voltage, with NV, it is showing you what the core voltage + the percentage is, but it goes down from that voltage (pretty sure)

2a. VDD if I am not mistaken is your LDT Bus voltage. The other one is your CPU Core

2b. Do you have a RAM Divider? If you have no divder then your RAM is running faster.

3. Well, you can get TCCD past 300HTT (DDR600 PC4800), but not all TCCD chips can do that, At DDR600, your timings are usually around 3-4-4-8

4. BIOS, VID Core will give you a base core and then the option below you can increase the base core by a percentage, 104% 110% Etc...

5. I answered that already, look at question 2a

Thanks, I'm going to fiddle with it more right now.

Update:


Upped my vcore to 1.45 in the bios
Upped the RAM to 240MHz
Lowered the CAS back down to 2.0

Running Prime95 right now...looks good

What is your LDT Multiplier at? It needs to be at 4x and when you reach 250HTT, 3x.

 

[dolphumous]

It's on AUTO

 

[iSkylla]

Set it at 4x. There should be 6 options, 5x, 4x, 3x, 2.5x, 2x, 1x. Set it to 4x and when you reach 251HTT, set it to 3x.

 

[dolphumous]

What's that going to do?

And how long do you run Prime95? Atleast 6 hours?

 

[iSkylla]

12 Hours once you have set an OC

It makes sure your FSB doesn't go over 1000

 

[dolphumous]

Changed it to 4x. Thanks for the safeguard.

I also think my Bank Cycle Time (Trc) sweet spot used to be 11 with my nForce2 Ultra.

Is that still the case?

 

[iSkylla]

I doubt it.
