E6750 & Gigabyte P35C-DS3R Overclocking Thread

[jaggerwild]

Hello all!
I'm not lost just wanted to plug into this thread as I have the same chip, got a lot of reading to do to catch up.Different board I know but same make, like all the info you guys have and have been reading it already. I started on this site with the "where are the gigabyte N680SLI-DQ6" posting they have a ton of info and were some very civil people too.
Love my E6750, but as I have read I guess my ram is holding back my clocking it more. I have had it to3.8Ghz yesterday but as soon as I tried to run a program things went south fast. Way to many options in this bios, witch makes me love and hate it too.
Again thanks for any and all help also I do try to help so!
Peace out!

Hi - why do you have a sad face in your sig next to the X1950Pro...?

I'm thinking of getting a better card for gaming as my HD2400 isn't a gaming card and was looking at that card as a good VFM stop gap!!

Are they crap? Most reviews I've seen say the opposite - not exactly 8800GTX's but more than ample for most of todays games.....


Hmmmmm

Have you tried the new F8 bios yet? What are the new vdimm voltages? Should I flash the F8 or just wait for F9? :laugh:

I did try this for you. Cleared cmos, did a "fresh" install of F8. VDimm moves to 2.128 when +0.2 is applied. C1E is still messed up in F8 - once again, I moved to F2. My VID drops in Core Temps to 1.0750 from 1.2875 and voltage falls to 0.963 at idle using F2. Using F8, speedstep lowers the multiplier to x6 (as it should) but voltage stays up around 1.32.

Regards,

Thanks. I guess I will wait to still wait F9 does I'm still on F4g

Well, when i had a p4 ht running at 3.0 ghz the x1950 pro was great compared to my x600 that my old comp came with. with the e6750 core 2 duo performance doubled. i can now run battlefield 2142 with everything on high at 1280x1024 with 4x AA and get around 60fps WOW. couldn't do that before. but now there are games coming out that push it and the x1950pro is showing it's age. i don't need latest and greatest but i would like a newer more powerful gpu for under 300 dollars like the Nvidia 8800GT. my numbers would go through the roof on everything my crysis with that card

if you can spend more than 200 there is a better choice to buy. but below 200 the x1950pro is probably still a player and you would play crysis on low/medium settings to your taste and more games before crysis with mid to high settings. it still has some life for the low budget crew. you want something you happy with 6 months after you buy...get an 8800gt. i'm getting one in january or february. at that point i would have had my x1950 pro a year

Hey guys, i am running f8 bios on my p35c , did anybody notice that High Speed Dram DLL Settings [option 1] is no longer an option in the bios. i was going to give that a try to see if i could overclock higher but it is not there. not that they ever explained what the freaking thing did.

Thanks for the info

I need a fast PC for video rendering and conversion etc, that's why I only had the HD2400 - but I've got into gaming a bit more lately - on my son's Xbox 360.

I don't wanna spend much on a replacement gfx card just yet, as I'm hopeless at PC gaming with the keyboard after being used to the Xbox handset for gaming control - I'm always DEAD by the time I've looked down at the keyboard to see where the 'Shoot' or 'Run' key is

I've found some emulator software so that you can plug your Xbox controller into the PC and map the walk, fire, move (.......or whatever-you-want) keys into, so it's like playing with your fav console handset.

Seems to work OK on the only PC game I have - Rainbow 6 Vegas - only trouble is, coz the gfx card's so slow - it's un-playable atm

I was thinking I'd go for a Radeon X1950Pro that I can get for about £70 quid off ebay etc; just to see how I get on......if it's OK - I might THEN think of getting a super-dooper one!!!

 

[mrfatboy]

I thought I would pass this little bit of info on everybody.


About 4-6 weeks ago I noticed that I was not able to reboot my system unless I turned the power off at the back and waited 10 minutes. When I tried to reset it it would go into an endless reboot. The fans always stayed on. I thought I had the dreaded "cycle reboot" problem. After the 10 minute wait it rebooted at stock settings than I was able to OC back up to 3.6.

It seemed like a heating problem to me so I checked my Northbridge heatsink. Guess what, it was not on all the way. Many people in this thread have posted that the heatsink was off or very loose when they got their mobo. I just never bothered to check since my system ran cool and at 3.6 very easily. I just snapped it back on and my reboot problem went away.

So the next time you are in your system make sure that heatsink is on firmly

@mrfatboy - nice tip - let's see if it helps some folks out. Speaking of that Northbridge, man does mine get hot! Whick musy mean it's seated reasonably well, but wow does it get hot - almost too hot to touch. Anyone noticed this on their P35C's? Anyome tried to do anything about it? Fan? Antec spotcool? New heatsink? My overclock remains very, very stable, but still....

Regards,

 

[mrfatboy]

I need to remeasure the temps on my Northbridge. I posted my original NB temps in the the OP. But since my NB was partially off they are now bogus

 

[mrfatboy]

@conjugal

Since you are taking up the charge on the Bios updates would you like to put together a summary of what they all do and don't do? I will then post that info in the OP for quick reference for everybody. If want to do it just PM me with the summary.

@everybody else

Let me know if anything else can be included in the OP.

thanks

rainbow 6 is probably old enough for the x1950pro to manhandle but like i said the 8800gt is the way to go. for about 100 more dollars when the supply catches up. here in the states the x1950pro goes for $175. the 8800gt is very close to what used to be top of the line. it performs almost like a 600 dollar card man. if you get the x1950pro and you play some newer pc games on your machine you will wish you had the 8800gt. if you can wait till january the 8800gt is the card to get. if not and you just wanna play one game right now then the x1950 pro will get the job done...it still does for me...but i want more. it's the weakest part of my system.

I'm thinking about getting one of these Zalman's for my overclocking adventures to come. It seems to have excellent reviews, and being that it is all copper, I don't doubt it one bit. Does anyone have one of these?

[mrfatboy]

This is better and the same price

the scythe ninja gets it done real well. i'm doing 3.6 ghz on my overclock and highest temp is 63C on 100% load with Prime95...doing gaming it may go as high as 52 or 55 which is within stock temps. i payd 33 for it on newegg 3 months ago...if you patient it may go on sale again but it's still a good deal at 40 bucks. ps i did change the fan since the stock one maxes out at 1200 rpm, i got one that goes to 1800 rpm's when 100% is load is on.

 

[mrfatboy]

I eeked out 20 more points in 3dmark06 but adjusting my memory timings. 12828 3dmarks


and yes, i was bored

is north bridge temp same as temp 1 on speed fan???
is that also same as case temp?
just need some clarification on what's what. Thanks

Regards,

how are you measuring northbridge temp? and what is considered hot?

 

[mrfatboy]

Speedfan and other apps don't measure NB temp. The bios (at least the older version did) measure NB temp at stock. So that is basically worthless for us OC'ers.

I use a digital thermometer placed in between the fins of the heatsink. I did that for the original temps in my OP. I seem to remember (fuzzy memory) that 105C was max but don't quote me.

Since I have had a couple of cocktails tonight I will redo the NB temps. It's either that or watch sat night TV.

Now remember, my original temps were done with the heatsink was not on all the way.

Give me 30 minutes and I will be back with more info

LOL, zip on it one time for me!!
so what the heck does temp 1 measure on speedfan? it hardly moves...usually stays at 35C to 42C. i remember reading your post before i bought this board, i made sure my heatsink was on there good before i assembled thanks to your post.

anyone know if there is a sensor out there to monitor ambient temp inside your case? recommend one that fits in a floppy drive bay?

 

[fausto412]

Talked to gigabyte about the voltage issues we see with these boards on ram. they said that the board only defaults to 1.8 volts on Vdimm when the ram is generic ddr2 800. so since my ram is OCZ platinum rev 2, it requires 1.9 to 2.1 volts, the board defaults to 1.9 and that is what throws off the voltages, can anyone verify this?

i know we all are performance freaks so we have performance ram. does anyone have some generic cheap a$$ ram to see if the voltage is 1.8 like gigabyte says and is upping voltage works correctly...ie +0.4 gives about 2.2 volts.

 

[mrfatboy]

ok, here is the info before I pour another cuba libre I was close. My idle NB temp was 104F. Not 105C!!!!!!!! C & F big diff. That's 40C for you metric guys My ambient is 73F.

Speedfan will measure

Core 0
Core 1
CPU
CASE
Vidcard

and Harddrive if it has sensors


youre temp 1 is either cpu or case. You will have to give me all your temps to me to help me figure out which is which.

I will do a stress test with Orthos to measure NB temps now and be back in a bit

Off to the bar

 

[fausto412]

has anyone attached a fan to the north bridge? if yes, did it help? did you use the fan header on the montherboard? how did you install it? glue? size of fan? height and width?

speedfan gets the cores right and temp 2 is something cpu related because it moves together with the core temps. i think it's cpu temp. does the 15 degree offset apply to that also?

temp1 is the one that hardly moves...but the cooler my room is the lower it is. it is 36C right now. it doesn't move fast. so that may be case temp. what's your case temp? where is the case temp sensor?

 

[mrfatboy]

Running orhos now. 5 minutes into it. My temps are

NB 45C
HD0 25C
Core 0 55C
Core 1 55C
CPU 38C
Case 48C
8800gts 50C


I believe the case sensor is by the NB. The cpu sensor is in the middle of the chip above the cores from what I read. Don't quote me.

There are aftermarket NB coolers if you want to use them. My Antec 900 is blowing all sorts of air on the NB now. If you want something cooler you need to buy an after market. I'm not sure it's worth it.

I'm still at 45C for NB at 10 minutes
