My recent switch to C2D E4300 (from x2 OCed to 2.6)

[dannybin1742]

so i built a an x2 65W system about 2 months ago, i also constructed a dual radiator external water cooling setup, in short the cpu sucked at ocing and it hit a wall at 2.6ghz, no matter the fsb or ratio used. on another note is was a good setup to test my water setup, at 1.5V underload it only got up to 43C, under idle it sat at room temp (25C)

so i bought an E4300 (SL9TB) 2 weeks ago and a p5b (basic) from newegg; with my water setup i'm at 3ghz 1.35V (i have not tried lowering this, i just raised it to see how high the cpu clock will go) and at 32 idle, 47 load (fsbram 1:1)

are the temps high (i use mct-5 solution, not water)?

whats the highest voltage you can use with this cpu for prolonged use, i'm starting dental school in august and will most likely not have much money to upgrade this system for the next 2 years until my wife finishes nursing school, therefore i don't want to run the risk of buring out the cpu in the next 2 years.

I am thoroughly impressed. I have been an amd user for the last 8 years, and this is my first intel system. I'm going to flebay by amd stuff and probably not look back until barcelona

 

[cubeless]

how much for the x2 stuff? one of my kids' friends wants me to build him something cheap...

 

[PCTC2]

well, the temps are fine for a C2D. Mine, on air, idles around 34C and load around 47-56C load (Prime95 single/double instances).
they may be high, however, for a WC solution.
but you can probably use up to 1.45v comfortably for 24/7 use. 1.5v for less usage. Mine's running at 1.54v now and I use it 6-12 hours a day.
you shouldn't try to lower the 1.35v. you'll probably get some instabilities at a 1.2GHz OC.
and BTW, did you disable C1E, EIST, and Virtualization Tech?

 

[Agentbolt]

BTW, did you disable C1E, EIST, and Virtualization Tech?

On the E4300? It doesn't have VT. That and the multiplier are the only difference between it and an E6300.

I have noticed absolutely no difference in OC stability or ceiling by leaving C1E and EIST on.

 

[PCTC2]

now i know about the VT on the 4300, but on high OC's, the C1E can cause instabilites. EIST is really just disabled, as far as i'm concerned, to stop the throttling effects of the dropped multiplier.

 

[dannybin1742]

i shut off the C1e, and eist, i noticed that under windows the vcore would drop, and when you are running a high oc that might be bad

also the temps may be high due to the AS5 not being burned in yet

 

[Agentbolt]

You shut OFF those things and the Vcore DROPPED? That's an indicator your motherboard is not working properly. Turning them on is what might drop your VCore.

 

[imported_Truenofan]

i think he's stating that they went down when they were on.

 

[dannybin1742]

yes, when they were on, it would drop under no use, and when you need voltage to continue running a processor at a 1.2ghz oc, that would be a bad thing, right?

 

[dannybin1742]

hmmm,

i can get it to boot into windows at 3.1 @1.4V, asus probe says 1.35, but when i run orthos, after 7 minutes, the program crashes.

so i backed it down to 334 fsb (3.005ghz) and now orthos has been running for 30min without crash or error. i noticed the voltage under load drops to 1.31 is this bad? i also noticed that under load (small fft, orthos) the cpu goes to 56C! but the heat from my water cooling system does not even seem warm, whats up?

when my X2 ran under load it would say ~47-49C but you could literally feel the heat coming out of the radiator/fan. This is opposite, it says 56C, but the air coming out of the heat exchangers feels slightly above room temp, not nearly as hot

any thoughts?

the ram is rated for ddr2 667 and its corsair (made for overclocking), and i have fun it at ddr 950 before so i know its not the ram holding me back.

should i increase the fsb termination voltage? its at 1.3V and i cool the north bridge with a water block, so heat is not an issue for me

 

[chizow]

Not 100% sure on these Intel based boards, but from what I've been seeing, these cheaper priced boards tend to skimp on the chipset cooling, which becomes the limiting factor for OCs. On my 650i chipset MB, the NB is insanely hot....hotter than any other component I've ever touched. Its definitely limiting my OC, but I don't really want to spend $25-30 on a good aftermarket cooler for it. I did install a $12 Antec SpotFan over top of the NB heatsink and I picked up 25MHz on the FSB and 100MHz overall.

Thats odd, i get 45C under load using a zalman 9700cu with my opty 165 with 1.5v, was under the impression that water should be a lot better than that.

 

[PCTC2]

well, 56C under Orthos load is fine. Anything below 65 is really fine for most OCs b/c no programs people run will stress a CPU as much.
And the air seems only slightly about ambient because 1) it's moving (physics and heat transfer) and 2) the temps are read from the die/mobo (depending on program). the heatsink and the air do not heat up to that much. it's all just physics and thermodynamics. don't worry about it.
and try putting the FSB at 1.4v and push it to 3.1GHz again. it most likely is the vFSB causing instabilities and since heat is not an issue for you, just try it.

 

[dannybin1742]

i primarily am going to use this system for supreme commander, i used to be a total annihilation junkie, sort of still am, i play it from time to time still.

so 56C load is fine?

also keep in mind i am not using water, i'm using mct-5 which is a non-conducting liquid that has thermal properties very simmiliar to water.

thank god i'm using it because i noticed a leak after it had dripped on my video card, but nothing happened, i dried out the system for a day and cleaned off the card with isopropyl alcohol and fired it right back up. so it actually did what its designed to do.

 

[dannybin1742]

i'm still totally happy with 3ghz, how often do you get a $160 chip to do what a $1k chip does?

 

[PCTC2]

yeah. that all should be fine.
but your load for a liquid cooling seems a little high. i get a 50C Orthos load temp on my current OC (E6400 @ 440*8) on air (TR Ultra 120 w/ Dual Fan Push/Pull).
440/266=65% OC.
334/200=67% OC.
We have similar percentile OCs and your TDP is lower, so I don't know why your temps seem a tad bit high.
But the temps are still safe so don't worry too much.

 

[dannybin1742]

do you think i should reseat my block? also maybe the temps will drop after the as5 gets setup, its literally only been running for a few days, and i have not had the system on all that much, i just run orthos while i'm doing lab work (the computer is my office)

what is the correct amount of AS5 to put on and how shoul i put it on.

what i did this time was i squirted some in the center of the cpu, looked like a round button, then i set the block on top of that and screwed down the nuts that hold the block to the board. some people say you should put a line down the center of the cpu with the AS5 instead of a round button shape in the center

is it possible that the asus censor is just reading high? what else will measure it?

 

[PCTC2]

look at the top sticky thread in this forum on AS5 application (it's about stress testing).

 

[dannybin1742]

yeah thats got to be my problem, too much as5 and the heatsink may not be even tightened down, i'm just afraid to tighten it too much because there is no backplate like in my x2 system so the board will flex if tighten it too much

I got my $120 Venice 3000+ to do 2.75ghz which was only 50mhz from a $1100 FX-57.



Dont you love overclocking? At $120 I could give two shits if it burned out. I saved $1000!!!!

yeah but i'm a married grad student so $120 let alone $160 is somewhat hard to come by.

how much should temps change if the block is seated properly?

i know the north bridge and grfx card blocks are seated perfectly because the idle temps for the NB are around 24C and load is 28C, the grfx card is 26 idle, 32 load, which is why i think the cpu block may not be seated properly

 

[dannybin1742]

I think these chips just run hot, i took off the block, relapped the bottom, cleaned the cpu and block with 100% ethanol and applied the artic silver 5 to it just like the forums show, granted there will be a break in period, but the temps now are 30-31 idle, 56-57 load. so with burn in they may reach 28-29 idle, 54-55 load.

still seems hot compared to the conroe based c2ds on these forums, (though mine is running at 1.4V)

I may try another block, I have a danger den TDX on the way

 

[swtethan]

are those warm for water?


my BT is loading @ 61c

 

[dannybin1742]

well i know what my cooling capacity is, so thats why it seems high to me

 

[cubeless]

60c is warm... seems that a lot of folks are pushing the c2d's and running @ those temps... it's part of the "everyone can oc" wave... will be interesting to see if there is a rash of c2d failures come summer...

were it me, i'd try to get it down to 50c, max...
