The Unofficial ASUS P5N-E SLI 650i Board Thread

[Sukhoi]

I actually just left my Freezer 7 Pro blowing upwards. It almost works better that way IMHO. My PSU has a big 120 mm exhaust fan right there that it blows into, and with the HSF in that orientation it helps to pull air right across the northbridge HSF.

And on my RAM situation, sure enough running dual channel in the black slots is completely stable. I just did a 16 hour Memtest86 run with 0 errors. Both sticks are fine, both yellow slots work fine individually, but I cannot run dual channel in the yellow slots. Absurdly weird!

Thanks for all the replies. My power supply is on the bottom and blocked by a the floor of the case (faux BTX style). I am thinking I may need to get a new case if I want to cool this effectively. I like the Antec P180 but would need to get a new power supply as the OCZ Modstream's cables wouldn't be long enough. Any more suggestions on smaller heatsinks?

Measure width of your case. The Overall Dimensions for the Freezer7 Pro are 107 x 96.5 x 126.5 mm or 4.21 x 3.8 x 4.98 inches ZALMAN 9700 90 x 124 x 142mm. I have over a inch height clearence in my Ultra Grid case.

tried this, i can set the memory to those timings only if i leave FSB/MEM settings on auto, if i set them to 1600/800 for a 1:1 ratio, memory timings revert to 5-5-5-15-1T. guess my only option is to wait for new BIOS, which i will be harassing our asus rep (i work at a reseller) about.

i can set the fsb/mem settings to Unlinked, but changing the numbers seem to revert the mem timings that i had set under chipset.

You removed the Batt and jumped the pins on the clear CMOS header.

 

[jkcheng122]

yes.

[Core2]

Sorry to ask the same question twice. Some people think clearing the CMOS is just to pull the battery out and place it back in.Try 1066/667 with 4-4-4-12 2T or 1066/800 with 4-4-4-12 2T I had to bump up the NB voltage to 1.39 to run 1600/800 or higher at 4-4-4-12 2T ------- 1T would not even boot on my computer and had to clear the CMOS to get it to post again. Maybe re flashing the bios with the CD would help. Sounds like your bios is corrupted

 

[jkcheng122]

thanks, will try reflashing and post on how it went.

by reflashing with the CD i'm reloading the same version BIOS correct?

 

[Core2]

yes, I would clear the CMOS again after flashing just to make sure. The correct procedure is in the back of the manual on how to flash using the CD

 

[jkcheng122]

reflashing the bios didn't help, same issue persists. setting the fsb/mem 1600 and 800 made the mem timings to go to 5-5-5-15-1T again at a 7:8 ratio oc'ing the cpu to 2.4GHz.

 

[jkcheng122]

i changed the NB voltage to 1.39 like u did and upped memory voltage up to 2.1xx and can now get 4-4-4-12-2T 1:1 for 2.8GHz oc, thanks for the help, i think i will keep this setting until a new bios comes out that would allow 1T timings and better oc abilities.

 

[Core2]

Good, now save your oc settings in the bios oc profiles under tools I usually save my stable best oc as profile 2 and my stock as profile 1 I also have a Flash disk in which I kept all my good oc setting as well as bios and flash utilities and load them in the bios from the flash disk and if you copy boot files to it you can boot from it and flash the bios too. I had the similar scenario I was un stable at 400 x 8 at 5-5-5-12 and stable at 4-4-4-12 but I also had to bump up the nb voltage. What is your ram voltage suppose to be at 800 (manufacture spec)

2.1V and 2.2V is the max voltage under warranty.

 

[Core2]

You should be able to go up to 900/1800 at 2.1 - 2.2vdimm 1.325 to 1.35 vcore nb 1.39 Watch the heat on the NB and SB you need a fan on them at those oc's

 

[jkcheng122]

any suggestions as to what fan i should put on them? i currently have the asus chipset fan from my A8N-SLI board on the southbridge, but it's currently not plugged in (only 2 chassis fan plugs on the mobo, both used by video card coolers, i'm gettin splitters from work tomorrow) so it only functions as a heatsink atm.

will prob need a fan on the NB if i start to oc more, tho prob wont try until a new bios is out.

what's the highest vcore voltage for this board?

 

[Core2]

For the SB I put on the ZALMAN ZM-NB47J Aluminum Heatsink on it see my link in the above post and cooled it down tremendously (only warm to the touch now) I have two 120mm fans intake and exhaust that came with the case and I added one 120mm fan to the side panel of the case that blows on my VC and NB. NB gets very hot even at stock voltage, feel for yourself. I might take it off a put some artic cooling MX-1 on it. I think 1.6 max vcore voltage. I read over at the XtremeSystems Forums that they have had success in running 1T by moving the ram to the black slots

 

[jkcheng122]

again, thanks for the info.

i might put a zalman heatsink on the sb as well and move the fan to nb, how big is the chipset on nb to have a heatsink that size?

Thanks for the 1T info ... It worked

Cheers

 

[jkcheng122]

yeah the 1T info worked. gonna get some better cooling for my heatsinks and try to go up from there.

as far as cooling for chipsets go, between a zalman heatsink and asus heatsink fan, which one should i put on nb and which one for sb?

If its like the 680i about one third the size of the SB

If your case has ventilation hole on the side panel you can do what I did. Attach a 120mm fan from the outside or inside and center it over the VC and NB. SB does not need a fan if you put the Zalman heatsink on it and does get some air from the side fan too. My other two case fans provide enough airflow to cool everything else. I use speedfan to control the two case fans and leave the side fan on full speed. I hooked my side fan on the outside of the case and jury rigged an old AC/DC converter and a four pin molex connection to be able to turn it on and off as needed I drilled some extra hole to center the fan over the NB. I am waiting for those temp sensors to arrive and I'll report some NB SB temps. Good Luck

How about some bench marks jkcheng122 Seeing your in SLI mode can you post some 3Dmark 06 scores running at 825/1650 mine were 5693 single mode. MaxisOne Seeing your at 44412 1T can you do some Super pi 1 mb scores at 825/1650 mine were 16.93 @ 2T. Lets kick this forum up a notch with some results and findings. I think this board has some good potential to compete with much more expensive boards (Striker, 680i). The only problem that I can see right now is cooling the NB, wont know the temps till I get those sensor and find out what normal temps for the NB should be (anyone know) and a good bios update should help. SB is solved with the Zalman heatsink (cools it right down) Lets go to work!

i havent managed to push 825/1650 yet, not sure if i need to set mem to 5-5-5-12-1T/2T for that, but at 4-4-4-12-1T it is a no-go.

my 3dmark06 score for 800/1600 (2.8ghz on the e6300) is 8025 under all default settings.

btw, looking at the included parts for the zalman heatsink http://www.directron.com/zmnb47j.html, am i going to need to take the motherboard off to put this thing on (the nuts possibly needing to be installed on opposite of the board).

 

[MaxisOne]

Ill get back to you on the Super Pi When i get home

Cheers

Thanks for the score looks pretty decent. That is close enough for me.(forgot you have a E6300). I can rerun mine again @ 400 and drop the multipler down to 7. You would probably have to up your mem voltage if your having problems at 1T or go to 4-4-4-12 2T nb voltage is fine as I have clocked up higher without having to change it from 1.39. Watch for Vdroop it's pretty bad 1.32 vcore should do it. The Zalman heat sink is easy to put together, no need to take your board out. It is a little pain to line up just tighten the screws pretty tight so you can just about move the brackets and then set it place and adjust the brackets till they line up put some good thermal paste I use ARCTIC COOLING MX-1 Thermal Compound works as good or better than AS 5 and contains no metal, so no electrical conductivity. Then push the pins in and your done.
