ASUS P5N-E SLI 650i Thread

[dpawl31]

Well I am not able to give you advice on the RAM as I am not sure what I am doing yet either. I definately don't suggest putting all your voltages to the max, this board overheats in the chip department as it is, definately don't do that. The less voltage you can be, the better. Essentially voltage stabilizes the overclock. But other than that all voltage does is use more energy and create more heat.

Being you have value select I would say you are in trouble there. But I am sure it is doable, you just won't get your best OC for your processor.

You said you are using Freezer 7 Pro as well? Is it installed pointing out the back of the case? I had to install my pointing to the front because of the NB heatsink hitting the Freezer. I plan to trim the ASUS piece off the heatsink and install a small fan on the far right end of it. I have an old NB cooler from my old board I am going to thermal-tape to my SB. Then I will start to OC.

I definately suggest reading some of the tutorials and stuff lots of info on timings and things.

well, i figured out the ram thing...
i have my rig now running stable @ 3.4Ghz, with Vcore of 1.450 and ratio of 1:1
so far its not too warm...again under load bout 60C...
HURRAY...its going good now, just gotta find out if i can OC further!
thanks cya!

I am running 3.5Ghz w/ vcore of 1.3v and 5:8 divider. I am also @ 55C max.
I will have to start playing with my RAM soon. I always thought you couldn't go over your rated speed for ram... so if you are running that high on a 1:1, you have to be over 667. I really haven't gone into the memory aspect yet so I have set my specs to unlinked and manually set the ram @ 800.

[gtboi604]

nope, runnin my ram @ 486mhz, so im actually downclocking my ram...
FSB @ 243, which is ddr 243, ddr2 486...
so yeah, try gettin urs to 1:1....
havent benched yet...will keep u posted later.
gl, hf.

I am not quite sure what you mean.

My FSB is @ 250 (effectively 1000FSB)
If I were to go 1:1, the RAM would run @ 1000Mhz right? Isn't that DDR2-1000?
At the moment, I am @ 5:4 Because I am running 1000FSB:800RAM

I was told DDR being Dual Date Rate means if set to 800 in Bios, CPUZ shows 400Mhz which is really 800Mhz because of DDR? I am so confused!

[gtboi604]

ok, how bout i jus give u sum numbers considering we have the same CPU...
ok, the 820, has a multiplier of 14x...the FSB in the bios shows the 'rated FSB' which is divided by 4, bcuz its quad-pumped er sumtin. (dunt ask y, jus cuz)
Now, the ram.
Take ur 800Mhz ram, and divide that by 2, bcuz its DDR2. (dunno y)

so, if u took my rig for ex.
FSBRAM @ 1:1 would have to be the BUS SPEED (243) and dram (486/2=243)
NOW, i take my BUS SPEED (243) x multiplier (14) = CORE SPEED OF 3.4GHz
My DDR2 ram is actually running at a lower than rated 667Mhz (486Mhz), now bcuz im running a 1:1 divider.

Hope this helps a lil...

Ah, awesome. NOW! What is the purpose of running 1:1.
I just don't see how slower RAM runs better?
If I am running 250FSB and 400Mhz RAM, 5:8, why not? Will it run better with a 1:1?

[dpawl31]

This board is taking so much heat by the P5B guys and non-sli guys.
Could they be scared of our ease over 500FSB? Or jealous of the SLI option, for at least $40 less than they spent on their single PCI-E board?

hehe.

SO! I finally understand the RAM stuff, and from what I can tell 1:1 just offers more stability. So if I have a 250FSB, I should downclock my ram to DDR2-500 (250Mhz) to achieve 1:1?

Will that run better than my 5:8 250:400Mhz?

[dpawl31]

Don't they make other cards for the PCI-E? Like sound cards and such?
Dual PCI-E doesn't always have to be SLI right?
Can the other SLI slot be used as a PCI-E x 1?

KEep that RAM as you have it. It'll give a little bit better performance that way

And I have not seen you hit 500MHz on your FSB yet, although you refer to the 'easy of doing so'. you claim yourself you're only at 250 (which is halfway)

I tend to take 'professional reviews' with more than a grain of salt, and go with what happens in the field. If you hit over 500MHz on the FSB, let me know!

It's a promising board, and if it does as stated, it will be a serious competitor for the budget P965 boards (Asus P5B-E, Gigabyte DS-3)
