Just ordered 3700+

[milan03]

$689 from newegg. Was wandering if its possible to hit 2.8ghz with heavy air and not modded vnf3-250 chaintech mobo. I know its gonna be cg stepping but is that gonna hurt my gaming performance or its just gonna hurt my memory bandwidth? I've seen quite a few owners of this chip on this forum, so please share your experiances :toast:

[Mariachi]

You got a killer CPU! Congrats!
Ask for StormPC for his experiences with his 3700+.

Yeah the chip will be ClawHammer CG - oh and it's not gonna hurt your performance, in fact it's gonna add some few sandra MB's because of the enhanced mem-controller.

[milan03]

Can this chip compare neck to neck with fx53 (gaming wise) or its not even a contest?

[trans am]

The nice thing about the fx is that the multi can go up and down. The 3700 can only go down.

hey trans am, how do your like your asus k8n, I just ordered one yesterday

[milan03]

I guess fsb is what matters :)

So far so good. I go to the asus site everyday to check for bios and drivers. Go there and you may already know that there isn't a single bios or driver up yet. Not even the ones that came on the cd. wTF?!! The agp/pci lock works and that's why I bought it. I was going to get the Epox, but the vcore on the asus will go higher. Plus the Epox doesn't have firewire and I don't think it has holes for the chipset. The Asus has it all. You're going to love it! I upgraded from the original k8v deluxe. Some dude on this forum also has one with a 3700 and his multi defaults to 11.5 he can only set it to 12 (default) by using clockgen, but it always resets back to 11.5 when he restarts. I think Asus needs to get to work.

[dr^MiFF^]

great, thats what I wanted to hear :) as far as the multi problem goes, since the mobo is so new, hopefully we can see a bios update soon

[Kunaak]

2.8 on air is alittle lofty.

all A64's seem to max out around 2.6 on air, and sometimes alittle more.

the 3700 is a prime canidate for sub zero stuff, but not really much different then say the 3400 when it comes to air cooling.
thats always been my observation.

[Reflex1]

the vnf3-250 chaintech mobo doesn't have multi control in the bios (i think) so the multi problem don't matter to him :) you bought a nice CPU :D

[trans am]

I could say you should've got an fx53 and were silly to spend that much on a 754 processor, but to be honest, I'm just jealous. Nice.:toast:

[milan03]

well i already had vnf3 mobo.. investing in a new $200+ mobo is way out of my budget. Also im selling 3400+ and my old radeon9800pro to a friend to be able to buy this cpu. Hopefully it'll pay off. :toast:

[milan03]

Oh ya i have only 1 stick of 3500eb so with fx53 i'd need an extra stick too, and a mobo, and $110 for cpu :( were talking about $500 extra :slobber:

[trans am]

FX53 wont work with 1 dimm?

[milan03]

it works, but then its a waste of dual channel support and my money either way.

[HawainPanda]

lol, ah, how high could u get ur chip on air milan?

[milan03]

3700+ arriving tomorrow, but right now im running 3400+ @ 2.5Ghz. I did few few benches on 2.56Ghz but that was it. My problem is that my mobo still doesnt have adjustable multiplier settings in bios, but the new versions should fix that problem. So right now with 3400+ im @ 228x11 vcore 1.7, vdim 2.9 idle @ 40C full load 51C.

[milan03]

Hmm... installed 3700+ and the temps went up! Just idling at 56C !!! Is that normal for this cpu? Something must be wrong here... :(

[eclypse]

Better check that out and see if its seated correctly. Thats on a chaintech right? I thought i heard of a beta bios out there that fixed the bad temp reading.. 15 or something like that.

[milan03]

i have that new bios, but i read on amd forums that some newcastles and amd 3700+ have different temperature settings... something like 20C degrees more. Can someone confirm that with me?

[milan03]

Btw should i use 1T or 2T memory settings for higher clocks?

[mrflushysheaven]

2T will give higher clocks but 1T gives better performance

[milan03]

just tried a quick oc and while i could do up to 230x11 on 3400+ 1.7, 2.9 now i can only do barely 220x12 on 3700+ :/ Will have to play with it tomorow some more.

[ColdFlare]

Anyone know if all the 3400+ clawhammers are cg or not?

[milan03]

most of them are c0 few very few are cg.

[milan03]

Ok.. Im at 2.7ghz now. 245x11. High temperature reading doesnt seem to be a problem so far....

Good stuff.. can you run some 3DMark01 & superPI at 2700MHz ??

[milan03]

SuperPI was 34 and 3Dmark01se was 26960. I only have 1 stick of 512 running 2T mode 1:1 right now. Not sure what else i should tweak?

[milan03]

260x10.5 = teh Winner ! mem 1:1.

[BMORIN]

NICE CLOCK! Can that cpu run '01 at that? Stock voltage?

[milan03]

cpu 1.65 vdimm @ 2.9, chipset 1.8 27220 '01. this mobo takes any fsb/voltage i want :) I wish i had vapo :(

[blinky]

can u post ur highest pi bench on air

i remember stormPC almost hitting 2.8 on air or something

just as the new FX53s seem to be much improved silicon i think the same is true for this 3700+

[milan03]

the highest i went was 11x247 1:1 vcore 1.7 vdimm 2.9 and SuperPI 33sec. That seems to be the absolute limit for my cpu . Really not sure what can i do to make it run faster. :(

[StormPC]

How about putting one of these on it?

http://www.stormpcs.com/db2/00108/stormpcs.com/_uimages/MVC-002S.JPG

[milan03]

AMD Athlon(tm) Processor 2925 MHz !!!! damn StormPC you almost hit 3Ghz! How do you like that gigabyte mobo? do you have any water on chipset and gfx or only phase on cpu ? Any vmods on your mobo ?

[StormPC]

Just phase-change on the CPU. Everything else stock. I was able to run almost 3100MHz (screenie) but was only 3D bench stable to about 2960MHz at 1.69v (motherboard's limit).

No vmods yet. I wanted to see if I could get on page 1 with a stock aircooled VC and no vmods at all. Got #16 overall on 2k1 and knocked MDZCPA down one with his FX-53 S939 rig. I'll try the vcore and vdimm mods this week.

So in answer to this question? I'd say the 3700+ is just as fast in as an FX-53 in most games, and very nearly as fast in 3DMark, but in pi calculations and Sandra mem benches the FX-53 is clearly stronger because of it's DC controller.:D

[milan03]

True. I seem to be hitting the wall at about 2720Mhz. No matter how much voltage i give it to the cpu, which memory ratio i use, what kind of multiplier combination, i cant go more than that. My question is : Do you think that CPU is limited at that frequency or phase-change would brake that mhz wall? cause i use slk-648 + 92mm volcano, and i really dont think that heat is teh factor here. StormPC, id like your opinion on this :)

[StormPC]

Air can only do so much. Of course a decent phase-change unit will give you more MHz, but you have to be careful that your memory and voltages are not limiting you. Have you tried dropping your memory to 166MHz (5:3) and your LDT to 2x just to see if that gives you more MHz? You can also set memory timings to default, etc... to make sure it's not memory related.

2720 is a decent air OC though. My fastest 3D stable on air is 233x11.5 (2680MHz) but I can do screenies at close to 2800MHz with 1.69v. Don't run your vcore over 1.8v on air. At 1.9-2.0vcore on phase-change I believe my chip may do 3.2GHz+

[milan03]

yeah most of the time i put my memory at 166Mhz although i did ran 252x10.5 with mem 1:1 and it was stable. Also i am at 2x htt and really thats the limit. Running vcore at 1.7( should i drop it) thats the maximum setting in my bios, vdim 2.9, and chipset voltage at 1.9. Those are the maximum voltages my board can take without vmods. So Vapochill will actually give me more fps even though my cpu seems to be hitting the mhz limit?

P.S. I maxed out chipset voltage on my mobo when running 250+ fsb. Do I have to do that or its not necesary?

[StormPC]

On phase-change you won't have that MHz limitation.

I wouldn't use Vapochill or Prommie. Have PC ICE build you something. He's much more reasonable price wise and his coolers are better. He does OPP's cooling.

[milan03]

btw, whats currently the best (performance wise) socket 754 nforce3 250 motherboard. Also, which board has the highest fsb value? My current one goes all the way up to 400mhz fsb.

[StormPC]

Best is tough to say since I've only tested two of the four I know about. I'd say the Asus looks the best without mods. With mods they should all be good performers.

The K8NS BIOS goes up to 450MHz. Don't remember what the MSI goes to. I'm getting the Asus in a couple of days.

[Filter]

i just got a 3400+ clawhammer thats a cg from new egg.

[milan03]

i just sold my 3400+ c0 that was stable at 2550Mhz.

was that on your chaintech board? I just ordered one. Do you love it?

[milan03]

oh yes! :) The only bad thing is that i was never able to change my multiplier settings using clockGen (Bios change kinda dont work) untill i bought 3700+ with cg stepping. 3400+ was stable at 332x11. That board pretty much screams after you find a way to change multies. :)

doesn't the beta bios work? I thought that would enable you to downclock the multi? Sorry to crap the thread.

[milan03]

it adds the option "hamme fid" but if you change the settings in there most likely you wont be able to boot the system. It only changes using increments of 1x. In clockgen you can use .5 . Ive been running 270x10 no problem.

[milan03]

I wander if water cooling would give me more Mhz on this chip. If so, which Water setup is the best performance wise? What do you recommend? I ultimately wanna get phase-change but it cost too much and uses so much electricity :(

[milan03]

anyone?

look at my sig. 1/2id (inner diameter) everything. mcw6002 is big enough to cover a pelt, if you decide to go with a water TEC setup in the future.

[milan03]

Whats your OC with that setup? How much more Mhz is that setup gonna give me over my heavy air? Trans i see that youre in nyc, is there a place in nyc that will sell/install water or phase-change to my system?
Thanks :)
