Re: ep45-ud3p 8gb fine tweaking...

that is a solid choice for psu!! everything i have read about it makes it seem amazing!!

very efficient which will be nice for your hydro bill/environment ;)

Sigh.....just another lemming following following the pied piper of Corsair band wagoon.
OK, so the Corsair models have outstanding reviews from the sites that really matter; JonnyGuru, HardwareSecrets, PC Perspective and others who really test the hell out of them and push them to see if they still meet their 80+ rating levels at 45 - 50 degrees (C).

• So what if the 750HX meets its 80+ Silver rating at full power at 45 (C)....yawn.
• And it puts out 912.7 watts at the same temperature with 83% efficiency.....eh.
• It comes oh so close to an 80+ Gold rating.....hmmm.
• OK, so its got outstanding voltage stability and very low electrical noise and ripple.....just like all the top tier units.
• What about the bling factor? Gotcha!
• 7 year warranty..... ho hum.

It makes my 750 watt Antec TruePower New TP-750 feel so inadequate.
Oh, wait a minute, I bought my psu on cyber-Monday with a special 2-day-only rebate for $70.... never mind

Here is my windows experience index....I am assuming that 5.9 is the max I can get on the hard drive - for a single sata drive?

Does the avrage user care for calculations per second, and disk speed, do they sit copy files all day?
Totaly meaningless number IMO.

[arctic-k20]

Re: ep45-ud3p 8gb fine tweaking...

they are all meaningless numbers pretty much - just curious what it would take hardware wise to increase that 5.9....probably ssd or raid

[Chike]

Re: ep45-ud3p 8gb fine tweaking...

A good SSD in raid0 configuration.

arctic-k20: When you set Performance Level 9, did you first try to set it in Memset, or did you just input it into BIOS?

When I tried Performance Level 9 in memset, it froze my machine.

On another note, tried running my RAM at 5-5-5-12, but had errors, so went back to 5-5-5-15.

If you have attempted to change tRD from zero to another value, it's a known issue and was fixed not to let you do it.
Latest MemSet vers. will not change tRD from and to zero.

Re: ep45-ud3p 8gb fine tweaking...

Well, when I went from Performance Enhance - Standard, to Performance Enhance - Turbo, I went from not having any Perf Enh value in the field, to having 10 in the field.

Also, going from Std To Turbo, it made tRFC rise from 64 -> 68. Seems like a performance loss?


Going from 10 -> 9 in Memset, and system locked up.

Re: ep45-ud3p 8gb fine tweaking...

memset changes almost always froze the system so i always made my changes in the bios..

[HyperEX]

Re: ep45-ud3p 8gb fine tweaking...

Tried it in BIOS, system wouldn't post. Guess I'm stuck with 10.

Re: ep45-ud3p 8gb fine tweaking...

Performance Enhance = Turbo is NOT recommended while you're trying different overclock setups.
tRFC settings vary with memory speed, memory voltage, and the amount of memory used.
With DDR2 memory, tRFC = 48 - 52 is often possible at 1066 speeds when using 2x2GB of memory.
With 8GB of memory, tRFC often needs to be increased to 60 - 68.
As I recall, 8GB of DDR3 memory often requires tRFC to be about 74.

When overclocking, my approach is to use:
Performance Enhance = Standard
Manually set:

• DRAM Voltage
• Primary memory timings
• Static tRead Value (tRD) aka Performance Level in Memset
• tRFC
• Driving Strength = 1 step higher than the memory speed (e.g. OC-1200 for 1066MHz memory speeds)

I leave the remaining Advanced Timing Control settings on AUTO until I'm ready to perform my final memory tweaks.

I always make changes in the bios.
