ROG V Gene, 2500k trying for 4.8

Tackle_Berry · 29 May 2013 at 12:05

Hi 8 Pack,

Hoping you could help me, I am trying to get my 2500k up to 4.8ghz. I have a watercooled system with fairly good temps so higher voltage should be ok? This cpu only needs to last for 12-18months then I will throw it in a htpc at stock speeds until it dies.

Have the following spec:

2500k
2x 4GB HyperX Genesis Grey DDR3 PC3-12800C9 1600MHz
Asus V Gene

I have tried the following settings as a starting point and then thought I would work my way down the voltage but even with the voltage at 1.45v it ran intel burn test once (max temp of 62) without fail and then when I ran it a second time it failed and with Prime 95 it's seconds before BSOD.

VCCSA Voltage: Auto
VCCIO Voltage: Auto
CPU PLL Voltage: 1.75v
Auto PLL Overvoltage: Enabled
PCH Voltage: Auto
VRM Frequency: 350
Duty Control: Extreme
Phase Control: Extreme
CPU Current Capability: 130%
CPU Multi 48 by each core
CPU BCLK: 100
DDR Frequency: 1600mhz
CPU voltage: 1.45v
DDR Voltage: 1.65v
DDR Timings: 9-9-9-27
Spread Spectrum: Disabled
LLC: Ultra High
C3 and C6 Report: Disabled

Sounds genuinely like you have a bad chip. Did you try for say 4.6 at 1.3 or similar first and get that stable. You dont play IBT or prime so use em sparingly.

This is my advice to you. Update Bios, the latest is good!!!
Set XMP for memory.
Then in Power section set LLC to high.
Set multi to 46 first
Vcore 1.35v
VCCIO 1.05
VCCSA 1v
DDR 1.65v
PLL 1.9v

In the memory section enable Maximus Tweak mode 1

Try get this stable and see how it goes. Adjust voltage sparingly and play with PLL as some like low PLL 1,45 - 1,35v

It may also be a good idea at this stage to run Memtest at XMP too fron Dos to make sure your DIMMS are good.

I have the latest bios, I will have a go with those settings you gave thanks, will also run a memtest.

I managed to do a quick clock to 4.5 when I first installed the board using everything on auto apart from the following.

45 multi by all cores
vcore: 1.36
mem frequency: 1600
Dram: 1.65v
9-9-9-27

The above ran 10 loops of intelburntest fine.

When you say 45 (by all cores) does that mean you using turbo and not the multiplier?

I though it was the same? I got no idea with overclocking I have just started reading guides last few days. This is the current settings that I done when first getting the board as mentioned above everything was a default apart from this:

45 multi by all cores
vcore: 1.36
mem frequency: 1600
Dram: 1.65v
9-9-9-27

Just done 2 passes of memtest with xmp, no errors.

Ok. Your doing fine!!! Keep going !!!
