ASUS P5N-E SLI 650i Thread - Page 223

post #2221 of 9621
Would an 80mm be to big to mod onto the NB, or just stick to the smaller 40-50mm? I would consider just throwing some AS5 and a heatsink and the SB, and the fan on top of the NB.

The wait for 7/22 is sooooo long.

Hello all,

I just purchased this mobo along with an E4300 (batch L651B680) and 2GB of Kingston DDR2667 with Elpida E5108AGBG-6E-E chips.

CPU has a Scythe Ninja Plus Rev B.
I replaced the NB hsf with an HR-05.
I added 2 chrome plated copper heatspreaders on the RAM sticks.
Added Thermaltake CL-C0025 copper ram heatsinks on the MOSFETs

I spent most of the day yesterday playing with it and oc'ing. I'm running pretty stable at 390 FSB x8 multiplier, 1.4 vcore, 1.56 vnb, 2.08 vdimm and 910MHz 4-4-4-12 at 2.08 vdimm (yeah, those Elpida chips surprised me too, especially since i paid 38 pounds for the sticks). Bios is 0401.

However, that's about the highest I could get stable. It looks like I can't get over 3.16 GHz on this CPU no matter what I try. I tried x9 multiplier and lower FSB, no luck. Any FSB above 390-395 will not even post and any combination of FSB and multiplier resulting in a freq above 3.16 GHz will not post either.

I followed many guied and tips for this mobo (including the one at anandtech), tried raising the voltages (reached max voltages), lowered dimm timings, etc. The above two limitations seem to be omnipresent no matter what I do.

If anyone thinks I'm missing something, please let me know. If not, is the above 395 FSB limitation be caused by the mobo or the cpu? The 3.16 GHz one is clearly the CPU I believe.

Anyhow, 3.12 GHz is fine by me on this CPU but I would have liked to use a higher FSB.

Cheers

p.s. I am for now testing this mobo and will have a chance of getting a P5K instead (not deluxe or -e, the bare p5k). Anyone knows how the P5K compares to the P5N-E in terms of stability at high overclocks?

Hey mastabog. Could you please fill in your system specs under User CP, Add System.


I have a confession. I took the easy route and put the 4 extra RAMsinks I had on my SB. I shall take any punishment Pook and pawl see fit for me.

Atleast I'm ready for that second 7600GT now. Something I saw, which I did not predict. I'll only have one open PCI slot. I already have a TV card in one. So if I get a sound card, bye bye TV card. :'(

PS. The RAM sinks don't look bad, they are a bit skew, but who's looking anyway?

Try Auto on the Vcore, and set the Vcore Offset to +100mv. Go at the CPU first then clock the ram up.

Ignite- I have a 60mm and it's about as wide as the heatsink. 80mm probably too big.
Don't try and spot cool it from a distance. Most 80mm are so low CFM... the airflow would get lost in the cross section of the case, well, at least it would in my windtunnel. lol.
Stick to 30/40/60 that you can fit RIGHT on the heatsink, as to get the airflow going right to it.

OK- first off, did you set your RAM timings/vdimm manually?
Second- what BIOS are you on?
OK now, I believe the stock multi (9x) is your safest bet.
Start from stock at the 9x. Remember, the 4300 is the lowest C2D, don't expect it to do 4Ghz. I know a lot of people have tried volt modding etc (madmax) to get it over 4Ghz. I am not sure at what point he had to do that, I don't even know what a NORMAL acceptable OC for a 4300 is.
I know they have trouble with higher FSB, so stick with the 9x.
The other main thing I noticed: why are you running 390 FSB and 910RAM?
Stability for Intel = 1:1. ie 390 FSB, you should run your RAM @ 390. (ie DDR2-780)
Remember, our BIOS displays effective values, so for 390 1:1 you'd need 1560 FSB and 780 RAM. But- remember the 4300 doesn't like higher FSB (from what I've heard) So maybe try 9x multi and lower FSB, with manual timings/vdimm and 1:1.
Start with 350FSB x9 = 3.15Ghz (DDR2-700 in BIOS, FSB = 1400)
I think you should be rock solid stable with that - as long as your timings and vdimm are good to go!
Also note- SYNC mode is 1:1, or you can just use full manual and type them in yourself (which I prefer)
Oh, and have vcore set to, I'd say 1.4v, but I could be wrong (I don't have a C2D!) But I think 1.4v is safe for you, and should allow you to hit 350x9 easy.
And remember, you have a northbridge voltage (MCP) you can adjust. 1.3xx and 1.5xx are good, 1.7xx is probably not neccessary with a 4300, if it's really neccessary at all (hah... Pook... )
Oh, and add your system specs, and welcome to OCN & the P5N-E Club!

Are your 7600's huge, because mine aren't. lol. I can't believe you lose those slots... ?

I believe this is it, but the one I have is intel - http://www.newegg.com/Product/Produc...82E16835150018

That looks like a 30~40mm, not 40~50

Double post FTW! hah.

The e4300 are pretty good overclockers from what i have seen myself. Mine has hit 2.7ghz stable at 1.3 volts. So 3.15ghz wont be to hard (havent triend becuase im on stock cooling atm) i dont think 1.4 v will be need. But it would help if he gave us the week of his cpu to give him an estimate.

Don't be hating.

The Zalman VF900 takes up one slot next door. So I lose the PCI slot next to the second PCI-E slot. Maybe if I kept stock cooling it wouldn't, but I already ordered a Zalman VF900. >_> Wanna overclock too, so yeah.

Hopefully I get it Tuesday!
Already scoring 3800+- in 3DMark06, hoping to hit atleast 7000. I'm sure my score won't just double up, but I should be able to manage 7000?

Also hoping the Antec TriCools aid in cooling my CPU. Wanna overclock more. Otherwise, moving to C2D when the prices drop. That will be my very last upgrade for sometime then. Cause I just dumped a lot into this rig in the last month or so. The P5N-E SLi, the OCZ PSU, and the things I'm waiting for now.

Of course the 805 will be donated to my folding rig. Haha.

Is here anybody who has been trying to clock his P4. I was just testing the new cooling system and therefore mounted my old P4 640 (3,2Ghz). Before last night, my rec was 3,9 with that one.
During last night a lot of weard things happened. There is no problem to load at 4.2Ghz. But then .... Between 4,3 and 4,7 Ghz there is no response. It just does not do anything or beeps. But there is 50-50 option to load @ 4.8 Ghz. But have not been still able to make the screenshot because just after the win start I see blue screen. And the codes are: faulty IDE device, network adapter etc. Noone of them is related to mem or CPU.
Sadly, that CPU does not take more then 1,58v. It just does not do anything with higher volts.

http://valid.x86-secret.com/show_oc.php?id=208710

Thats the clock when the rig is benchable.

It seems I'm having a new problem now. When I run Orthos blend stress test I get the classic "Rounding was 0.5, expected to be less than 0.4". I haven't got that one with my new system before Any idea to what could be causing it? It's a problem with the RAM right, but I'm pretty sure I haven't done anything to it since I last ran the test and got no errors. They're running 750MHz with 4-4-4-12-2T with the voltage around 2V :/

Also, it seems I'm stuck at my 3.375GHz. Load temp (stressed with gromacs core) is around 60ºC, and I won't go any higher, so I'm trying to tweak the voltage. Right now it's getting 1.4V in BIOS with +100mV on, meaning 1.5V (which is what everest and pcprobe reads), and I think that's pretty high for less than 3.4GHz. If I take the +100mV off it can't get past the POST screen, so I tried upping the voltage from 1.4V (keeping the +100mV setting on auto) to 1.41, 1.42, 1.43 and so on up to like 1.48V but it's not stable at all no matter what I do Perhaps I should try to go below 1.4V in BIOS but having the +100mV on. Perhaps this chip is just really voltage hungry
