[rubber5]

Hoss331 is exactly right

Rubber try touching the south bridge heatsink whe everest shows 60c.i bet it will be very warm
my new UD3R rev 1.1 SB H/S is very hot compared to my UD3P

I have touched the south brige heat sink but its really cool so it cant be oveheating since the northbrige only gets warm im happy about that now thanks

do you see any difference in your games when you overclock your cpu becuse i dont is there any reason that is happining

8GB (4x2GB) RAM - EP45T-UD3R - Q9550 - CPU FSB : DRAM 1:2

[bluestang]

Is the 333 strap 2.40B broke at 500fsb with th F9 bios? Should I go back to F4 or F6?

[radaja]

well i dont know about F9 but i do know that when running 2x2GB kits its sometimes can be hard to do but now impossible.

anyway i decided to give my new cpu a go at OCing with the stock heatsink,and i got to say im quite happy with my new cpu.
after i had to sell my awesome E3110 that could do 4250 w/1.24v-1.28v depending on the multiplier,im glad to report that my
new E8400 has gotten off to a good start.i dialed in some of my old settings from my UD3P and first try i got this.



i stopped it cause it was getting hot(have to adjust my airconditioner vent hose)will try again after i reconfigure some things
and some strategic fan placement to see if i can keep the temps down so i can prime for at least an hour.

[Loco23]

As far as I know there is no nb temp sensor on these boards, just one close to the sb.

To monitor NB temp use MCHTemp.

[Hoss331]

To monitor NB temp use MCHTemp.

The temp sensor is supposedly by the SB not the NB.

do you see any difference in your games when you overclock your cpu becuse i dont is there any reason that is happining

well i dont game so i cant speak to that,but i would think that OCing the GPU
is what might gain you more FPS.but then again i really dont know,sorry.

well after some rearranging i got it to prime for over an hour
im going to try and lower the vcore some more and see what i get.
very very happy with this new cpu

[bluestang]

well i dont know about F9 but i do know that when running 2x2GB kits its sometimes can be hard to do but now impossible.

Thanks radaja, I have 2x1GB kit. I think I'll go back to F6 and give it a whirl. I really want that 500 FSB as the memory scores are so much better.

What is your CPU reference? Cause mine is at stock which would be .760 if the VTT was at stock 1.2, and I need 1.328 vcore at that same speed (4.250ghz) to make it stable. Does increasing the CPU reference really help lower the vcore, cause I haven't tried increasing it.

bluestang,yep memory scores are much better indeed.i wish i had a set of d9's right now so i could test out my new board at 2.40B ddr1200.
my first one did great at that setting but my replacement for the first not so good.so i am curious as to how this UD3R will do.

Dark-Energy,for these runs my cpu ref is set to normal which sets it to 0.76
mch is at 0.70 at 1.20vtt and my vtt is at 1.26.as to helping to lower vcore it can by a notch or two.
but i think it mostly comes down to how good your cpu is.my 1.25vid cpu needed 1.34-1.36v for 4250
but my lower vids needed 1.24- 1.28v.

well it seems that 8.5x500@4250 w/1.28vcore works just fine



and 8.5x506@4300 w/1.28



and 8.5x512@4352 w/1.28v



gonna try for 4400 w/1.28v

[Ghostleader]

@ Ghostleader ... how is the Rampage Formula with Dual Cores in overclocking?

I just love it, most for it´s so stable, consistent and easy to tune in, i have abused it a lot and it always recover when I try to do some insane OC runs.

OC duals up to FSB 600, if you want to go higher I think you need a board with better setup, RF is to coarse.

On the downside are the heatpipe/sink for the NB, it´s not good enough if you intend to push it, recommend to go with a 3rd party heatsink with a fan or waterblock.

If I had to chose a good DDR2 board today I had probably chose the EP45-UD3R/P, some what better in overall, what about downside, hmmmm, it´s a bit more sensitivit to tune in though but once you have it tuned in and learned how it works it really rocks, don´t have 16x/16x PCIe but I don´t think that matter that much.

Otherwise I think it´s some what better in overall.



@pangingIII

Nice 4x2GB result you got.

Is it with those Crucial value?



@radaja

Looks like you got your hand on a good E8400, nice.

Have you got a new job or are you still searching for one?

[kagula323]

10x allot GhostLeader ... I'm currently on UD3P ... but had the oportunity to buy an RF at verry good price but .... I'm gonna say pas

yep i think i got a good one indeed
and im working for an employment agency right now but the company i've been working for the last three weeks is going to hire me on full time
im going to try and get 9x500@4500 today,but my cooling might not be up to the task.i've got a 4500RPM fan mounted on top of the intel stock heatsink
and the airconditioner vent hose blowing directly down from above it.to be
able to do 1hr plus prime runs ill have to crank up the heat in the house to keep the airconditioner running full time(blowing the cold stuff)otherwise this chip will shoot up to 65c and beyond.and i dont like to go above 65C.
im hoping that i can get 4500 with less than 1.34v,otherwise i think ill have to wait till i get a new cpu cooler.but im gonna try

not bad at all.4470 w/1.31v FAILED ORTHOS after 25m


moving on.9x500@4500 w/1.32v . i think god finally granted me my very own golden cpu

[bluestang]

How much MCH volts will I need for 2x1GB rams @ 1200 mhz on 500fsb x8.5 ??

[radaja]

anywhere from 1.26 to 1.36.ive seen some do it with less than 1.30,also depends on what cpu(dual core or quad)

Nice to hear, nice to get some cash, isn´t.

Keep up the good work with your gear.

10x allot GhostLeader ... I'm currently on UD3P ... but had the oportunity to buy an RF at verry good price but .... I'm gonna say pas

Good idea to say pass if you already have a UD3P.

How much MCH volts will I need for 2x1GB rams @ 1200 mhz on 500fsb x8.5 ??

You shouldn´t need more then 1,24v but it depends on what tRD you intend to use, probably tRD 8 I think, I did run my E8400 @ FSB 500 x 8 2x1 @ 1200MHz 555 15 tRD 8 with 1,22v.

Hope this screenie can help some.

[radaja]

thanks Ghostleader.at 9x500@4500 w/1.32 its still running too hot for my cooling.
im going to move the setup into the bedroom because the airconditioner in there
blows much more cooler air than the front room one.if i can get 5c-8c cooler then
i can see what this new cpu can really do

Bluestang see,i knew ive seen some use much less mch volts.great work Ghostleader
with 1.22mch

[kagula323]

@ radaja
what vid and fpo/batch is your e8400?
and i please you to post a template when u get 4500 stable

[radaja]

kagula323,vid is 1.23 and batch is Q843A771.i got it from newegg last week
and heres my settings so far.i think the only thing i might have change
is the vcore.but ill let you know once i move the computer.

Well, I have just recieved my UD3P, the board looks nice, but like always Gigabyte thought that most of users are color-blind.
In comparison to my previous motherboard (ga-x48-ds4) this one have almost twice the options I had before. And that is good from a side and bad (just for now) from other side, because I dont know what does some of those options. And good because I can touch a little bit more.

I attach my Bios options, where I just move slightly some numbers.
And also I bring up (in red fonts) the options wich I dont know what they do, so if someone dont bother, could give me a little explanation.

Thanks in advance.

@ radaja and ghostleader...thanks I'll give it a try. BTW I'm running a dual core as in my sig.

[kagula323]

wow ... radaja ... u amaze me :P ... so quik u answered ... really apreaciate

[BuGjAE]

@radaja, So really cool You got golden CPU,I'm sure VID 1.23 isn't too hot for 4.5 on Air ,awesome clock with low volt

[radaja]

kagula323,no problem at all.thats why were all here to help and learn

BuGjAE,yea it seems to be a great chip.im trying to do 9x500 but its
just a little too hot.had to up my vcore to 1.34 and might need a little more
to get it to prime for more than an hour.dont know if my cooling can do it
now.

[Loco23]

The temp sensor is supposedly by the SB not the NB.

You don't understand me. A temp sensor is located right in the chipset, not on the board.
