my phenom940 benchies

Thanks for the superpi result.

My 5600+ @ stock 2.8 does it in 29.85. If I could clock it to 3.84 it should in theory make 21.76.

Your score of 18.62 means that your Phenom II rig is "clock for clock" 14.5% faster than my 5600+ rig.

At superpi that is & not overall.

Wprime is better with up-to-date code & techniques & multi thread which is everything that Superpi is not..

Can't use Superpi to compare anything but the same chips. It doesn't mean anything comparing a Phenom I to a Phenom II, never mind any other comparison

Me and Smirnoff had a trial with the 940 on Saturday.

Got very impressive clocks out of it with a bastardised Noctua N12 cooler, although the motherboards we were using were not up to the clocks the chip could handle.

4.00GHz on decent air in a cold room, until the motherboard gives in. x3.

i've ordered mine. will be getting it tomorrow. im so excited. this is the first product ive bought afew days after release.

What board? Did you put a heatsink across the PWMs?

The 940 and to a lesser extent the 920 are still a comical price on the site... Unless you were ordering a good few other components at the same time to balance out the price, I can't see any logical reason why you'd not hop over to a competitor.

You might have seen this but these guys have managed 6.16 GHz under LN with a retail chip. A very impressive result and they are going for more ...

Wow! The record for a 45nm intel dual is about 7ghz, no?

Very tempting, under £230 now.

Personally with everybody's opinion that these will be massively supersededby the ddr3 versions on a few months and dual cores being so cheap , I'm struggling to justify this much on a CPU.

There's always a new generation around the corner to make a saving on current gen kit, if you lived by that rule you'd never upgrade!

I'm going 940 for my main 'fun' rig and my current 5000BE will be undervolted to run in a silent 'work' rig for my stock trading.

I was looking over at xtremesystems and so far the top 10 overclocks on air and water seem to range from 3.8-4.5GHz, mooooore than enough to last a few years yet, for me I see no reason hanging around for AM3 or any Intel platform, the 940 is strong enough for some time.

gareth170 · 13 Jan 2009 at 18:24

i have my 940 installed. its very fast. haven't tryed overclocking yet. my board doesn't show the cpu name., theres a beta bios that fixs that but i don't want beta. but tbh it just the name so no point.

yup, however the i7 quad's have only got to 5/5'2Ghz so far for I believe anything which means when talking about a slightly more complex chip with various bits running different speeds, uncore's several layers of cache and the cores themselves, AMD are doing pretty damn well with their first batch, the lower power new stepping can only really do better tbh. Could be looking towards 7Ghz with the new ones methinks, and over 6Ghz 3d stable(afaik they are benching 3d at around 5.6Ghz, I believe same goes for i7, fairly big drop between stable 3d benching and a super pi type run.)

As for being superseeded, clock for clock, don't expect too much from ddr3 tbh, and the 2Ghz northy, from 1.8Ghz will do some, but if you can overclock a current northy to 2.4/2,6Ghz anyway, it might not matter. power/clocking limits will be the main difference I think and they won't be "that" huge.

The most interesting thing will be further lower down the range cpu's being released, so you can grab a much cheaper AM3 when they are available, get a 2.4Ghz one or something for hopefully not too much more than £100 and clock the jesus out of it

i've tryed overclocking it just by upping the mutilplier, heres what i've found, in vista 64bit i can only get to 3.4ghz on sock volts (1.35v), on 32bit it can easyly get 3.6-3.7ghz+ on sock volts (1.35v)

but i'm still very happy with it. its so fast even at stock. and the temps are great 26c idle, 35 load @ 3.4ghz.

The Phenom 1 chips had huge differences between 64-bit and 32-bit too, i really struggle to find a logical reason as to why AMD did not resolve this in this iteration.

Where's these benchies that Mattymax promised us then?!!

It's hardly huge differences now, I don't think they need to do anything to resolve the situaton. Makes sense to me that the OC would show up as a failure quicker if in a 64bit environment...

hmm, been having some issues with my DFi mobo, for some reason when I try to do the update from Vista to, Vista again(to use the upgrade product key I have) it simply won't let me, errors out every time for no reason. Windows 7 installed fine so trying that at the moment so I can't really compare stability/overclocks easily.

3.8Ghz is pretty damn easy, almost on stock volts, though running higher volts at the moment to see if I can get further or increase stable overclock of HT or NB.

NB 11 multi runs fine at 220 or below, giving about 2.4Ghz NB, and you certainly see a drop in latency and an increase in performance. As to cpu scaling, I haven't run much yet, but 3dmark03, with a 4870x2, goes from 56k stock, to 83k at 3.55Ghz or so with the northy at around 2.4Ghz which is not at all a bad increase. likewise 05 went from 16k to 25k ish i think.

The HT multiplier doesn't seem to work on this mobo so can only increase it via increasing the HTT bus speed, this is fairly hard to do with lack of memory dividers and cheapo £40 4gb set, 225Mhz is fine but higher and I start to have problems.

So far what seems almost rock solid is 3.65Ghz with 2.35Ghz NB and 1.95Ghz HT. Theres issues with certain dividers/multi's with this bios on the NB/HT so finding a trade off is what I'm doing at the moment. Thing is in general with p1's the idea was the chip didn't run well with the HT less than half the speed of the cpu. So you're set to 3.6Ghz, after that you really want to bring the HT speed up to 2Ghz or more to go higher more easily.

Much as I've always liked DFi this board is doing my head in, might just be a slightly duff board and a replacement would be better, not sure tbh.

I'm barely kicking out any heat from the cpu at this speed/voltage though so 99% sure it has a lot more overhead in it, just not sure I'll get it with this mobo.

what OS did u use 32bit or 64bit?

always just so u know amd site says the 940 can run at 0.875-1.5V and max temp of 62c (not sure if that means core temp).. but the voltage range is great.
