ASUS P5N-E SLI 650i Thread

[SovereignRedoubt]

Oh, ok, hehe, sorry, I'm not sure what to change really any settings to, or if to at all.

[SovereignRedoubt]

What should I change the Vcore Voltage, the Mem Core Voltage, MB Core Voltage, VCore Offset Voltage to? Or should I change these at all?

[Awesome]

Uhhh only change the voltages after you change the clocks, and only if you have to. Erm I don't remember what the names of the things to change are. There should be an overclocking guide on the first page of this thread.

[SovereignRedoubt]

Oh, okay, thanks.

EDIT: Do you change the CPU Multiplier? If so, what is a good setting for it?

[marsey99]

pcie clock can be changed as it will help your 3d scores, with 1.56v to the nb mine would do 125mhz.


guy with a e66, you need more vcore as 1.3v isnt alot.


guy with a q66, 3ghz is about the max you will get from this board sry

[SovereignRedoubt]

Yeah, I'm sorry everyone, I just don't really know any good settings, and my way around BIOS yet. So, sorry for myself being overly questioning.

I changed the nb to 1.56v, and I changed the PCIE Clock to 125 Mhz.

Now, should I keep the FSB Mhz at 1333?

[SovereignRedoubt]

Ok, whenever I play Crysis now, it starts, then it freezes, and loops whatever sound was just playing. I believe this is from overheating, but I'm not sure. Anyone have a solution?

[marsey99]

my mobo also has non stock cooling and a graphics card that can handle those speeds, you need to fill in your system specs in your user cp so its easier to understand your system.


your gpu might not take more than 110mhz, and if you only have stock cooling on the motherboard you might want to leave the nb at 1.39v.

[Armalite]

Alright, I set the FSB to 1333, set the Memory to 'Linked' Sync Mode, set CPU Vcore to 1.35 and it booted fine. Right now its idling at 28\29 c at 0-5% load on G15 LCD, with TMPIN0 33c, TMPIN1 28c, TMPIN2 25c and the CPU VCORE is at 1.42v according to HWMonitor, 1.34v according to SpeedFan, 1.34v according to Asus PC Probe 2. for some reason CPU-Z VID has been stuck on 1.300 V since I got the new version (1.46) even before attempting to OC.

CPU-Z is reporting in the Memory tab 'DRAM Frequency: 333.3 - 333.4MHz| FSBRAM divider is at 1:1. Below it says:
CAS# Latency (CL) - 5.0 Clocks
RAS# to CAS# Delay (tRCD) - 5 Clocks
Cycle Time (tRP) - 5 Clocks
Cycle Time (tRAS) - 31 Clocks
Bank Cycle Time (TRC) - 20 Clocks
Command Rate (CR) - 2T

(Just to remind you I'm using 667MHz ram at 1.8v)

I'll run a RAM+CPU(right test?) blend test in Orthos for about an hour just to see how it goes, if it doesn't crash I'll run it overnight (8-10 hours will be ok?)

This is on the stock Intel HSF. I will not be going any further until I purchase a ThermalRight 120 Ultra eXtreme HSF.

Sorry about the long post, just trying to get as much info for you guys as possible.
Thanks to anyone who can give me some help, it is greatly appreciated

UPDATE: I ran Orthos CPU+RAM blend test for 2 hours, and HWMonitor said that the cores got up to 55c max, most of the time they were running at 50-52c, TMPIN0 got up to 45c Max, TMPIN1 and TMPIN2 didn't change. What exactly do these mean? I've googled and have found that some people say TMPIN0 is the temp inside your case, TMPIN1 is the outside of your case, and TMPIN2 is the CPU.

nice post armalite, makes it easy to help

seeing as you have not overclocked your ram small ftt will be all you need to run to test your cpu.

tbh i think you should have no trouble running on those clocks with that cooling but im not sure you will get much more and stay stable.

1.4v is about as far as the stock intel blower can handle.

@SovereignRedoubt

same for you too m8, keep the nb @1.39v and unless you have great ambient temps i would keep the vcore at 1.4v too.

your cpu is a x7 multi so your going to find it hard to get a monster clock but i think you could get to 400fsb (might need more vcore?)easy but that will only have you @2.8ghz.
