that is a nice overclock, but at 1.6v it prob wont last but a day or so. WOW look at that cooler, IT IS HUGE!!!

Yowza, 1.6V for 45nm? I'm scared to put that much voltage through my 65nm chip, but impressive overclock nonetheless!

Reply to epsilon84

thats one mofo of a cooler, a bit excessive though

I agree on the 1.6v sounds like it wont last too long

Regardless of what it took to reach the 4Ghz mark, I am very impressed with the overclocking potential of deneb, especially compared to current phenoms. If AMD introduces competitively priced 790FX+SB750 it might be worth it over a P45 platform in some cases, if and only if they deliver on their other promise.

So I guess this kinda makes that 4.3GHz OC look untrue considering that this one alone needs 1.6v. Possibly on water or LN2 it may sruvive with 1.6v but I doubt it considering that current Phenoms can handle up to 1.6v and they have much wider gates than Deneb does.

Nice OC but hopefully better voltages by the final release.

What do you mean 'if' AMD introduces competitively priced 790FX+SB750 mobos? They're already under $200 at Newegg, which seems reasonable to me. Sure its a bit more than some low/mid range P45 mobos but I don't consider the P45 as its true equivalent since it only does 8x/8x CF, in terms of features X38/X48 mobos would be a better match.

 

Hopefully release stepping Denebs can hit 4GHz at lower voltages, because current C2Qs are hitting 4GHz at about 1.4V, which is a heck of a lot safer for long term usage.

It depends, if this is an 'average' sample then a cherry picked sample could conceivably do 4.3GHz, maybe they cranked the voltage even higher than 1.6V! :ouch: ;)

YIKES. At 2.2GHZ the volts are at 1.240. To get it up to 4GHZ 1.6 volts. That is one hell of a overvolt right there. Hopefully they can overclock to 3+ghz range with reasonable voltage levels(either at AMD voltage spec range or just above it).

Time will tell us soon what these CPUS can do at stock and how much OC headroom they got. Cant wait to see myself.

Reply to someguy7

So an AMD CPU can finally achieve a clockspeed (with conventional cooling).... its competitors have been achieving all these time.

None the less, at least its an achievement.

Reply to BadTrip

I know that the 790FX is the equivalent of the X38, however since intel has the performance lead and I don't see them losing it anytime soon, AMD needs to give an incentive to people for them to want to use a spider platform.

 

If they start pricing 790FX+SB750 to compete with the higher priced P45, then it might give people a reason to get a deneb and two HD 4850s over a P45 and a dual core/quad core.

 

I see those pics stating that the engineering sample was Stepping 1, and I think I read somewhere that the retail product will be at least stepping 2, so I'm guessing you'll be able to reach similar clocks on slightly lower voltages.

 

EDIT: Actually, I looked at 790FX+SB750 prices and I was mistaken, I saw Foxconn and DFI boards priced at $170-175, which is pretty damn good considering how feature-packed they are.

Regardless of the voltage, this earns AMD some respect in my book. I never thought id see a modern (not Athlon) AMD cpu hit 4ghz, let alone 3.6 or so so :D

What I find impressive about this, is that it started at 2.2Ghz and went to 4. The fact it was originally clocked at 2.2 means it's not even one of the higher binned processors. Makes me excited to see what one that starts at 3Ghz can do, shouldn't need such extreme voltage.

I build in the budget range and nothing Intel has interests me. My only regret in the upgrade in my sig is that I didn't wait and get a 790GX board with an 8850BE or 8870BE. Now, I'll wait and see what Deneb has out.

Currently, the boards that look really good in the 790 range are from Gigabyte and ASUS, but I particularly like this one:

http://www.newegg.com/Product/Prod [...] 6813131331

Even though I don't use an IGP as my primary display, I like them for emergency backup and troubleshooting. To test the value of the IGP, I removed my 3870x2 and played LOTRO. It did so smoothly with medium settings (whereas I get high settings with the 3870x2 -- almost certain the game doesn't use Crossfire mode). Of course, it won't play The Witcher or Oblivion, but AMD's IGP's are topnotch.

The only thing Nvidia's doing now that I believe AMD should do is include the IGP on every board, at every level, and implement power saving mode while surfing the net or watching DVD's etc.

I agree with you that the 790GX is an excellent feature-packed board. I am very happy with how many features are crammed into it for a great price point. (Seen the $99 Biostar T-Force 790GX? Now that's value!)

However, I was talking more about the enthusiast side of things who will want to make a spider platform, especially since ATI is the graphics choice for anyone who is looking to build a great system. Looking at this board paired with 2 x 2GB DDR2 1066, 2x HD 4850s, and a deneb CPU is looking like a juicy solution for people who want real bang for their buck.

Also if AMD prices their AM3 motherboards like those above, I wouldn't have much problem recommend DDR3 memory with the current prices... They are actually looking pretty competitive! 1.5v DDR3 1333 4GB kit for $125!

What I want to see is a comparison of DDR3 performance on Deneb boards vs. Nehalem. Correct me if I'm wrong, but the first Nehalem boards will only have 4 slots for memory, making one useless as Nehalem uses triple channel at very specific voltages. Will Deneb use dual channel DDR3? Will it support current performance DDR3 that would fry a Nehalem? Can't wait to see how it all turns out.

Every nehalem board I have seen has 6 slots.

Only the Intel mobo will have 4 slots. Asus, DFI, Gigabyte and Foxconn (the one THG has I think) will have 6 slots. Even with 6 slots you can still run dual channel DDR3 if you please but why limit the chip, I always say.

Okay, thanks for correcting that guys. I don't know why Intel would go with 4 slots but advise triple channel kits specified for Nehalem. Makes me think they're rushing out the boards or have some bios issues that other board makers are finding workarounds for.

The 2.2 you saw is from a ES chip, with a unlocked multi, so it can go at any multi within reason. Having read more on what Andrius said about the 4.3 clocking, he says it may well have been cherry picked, but I think 4 is possible, or will be with patience

Good point. If the 2.2Ghz can hit 3.2Ghz stable then that would be a decent overclock.

Reply to sedaine

2.2 to 3.2 would be fricking great overclock. Me thinks many folks have been spoiled by Intels c2d c2q and even AMD's X2 black editions.

A 1GHZ overclock on reasonable volts is a GREAT overclock if you ask me. And if the majority of the retail cpus can do it than that is one hell of overclockable cpu.

Reply to someguy7

someguy I have to agree with you there.

One thing that has really impressed me has been how the core2 line can sustain quite a considerable overclock without an increase in core voltage.

The 4400+ (2.2 / 2X1Mb cache) was the only other chip apart from the Pentium 166MMX I ever found that would sustain an overclock without extra juice to start with ... just me ... not what I have read mind you.

I think most who have a Q6600 have managed to boot straight to 333 (3Ghz straight from 266 / 2.4Ghz) without any extra core voltage.

Intel must have simply binned quality silicon right accross the range - simply setting the multipliers to confuse the n00bs.

Probably the only real speed deficient silicon is the real low end of the spectum.

That's good for us.

I was. In fact I was able to do it at a lower core voltage than the stock voltage. My Q6600s VID is 1.275v and I got it to run 3GHz @ 1.25v and Prime95 stable for over 12 hours. The Q6600 is a great chip for enthusiasts who want a decent OC and quad core.

If Deneb does do 2.2GHz to 3.2GHz that would be great. Just lets hope its not like the Agena based Phenoms with some getting 3GHz others at 3.2GHz and some that wont OC at all.

^ That was mainly because of the SOI 65nm process... leakages all round...

SOI ain't that good after 90nm

Hopefully, Deneb will be better. The Phenom had so much potency...

Reply to amdfangirl

^But Deneb is still based on SOI even at 45nm unless some report has stated otherwise. If it is still SOI then the leakage might get worse at 45nm.

From what I have read HK/MG from IBM themselves is slated to 32nm and AMD might do a respin of 45nm with HK/MG but not until later. The initial ones might still be SOI if thats true and hopefully SOI gets better at 45nm not worse.

^ We won't know until they release the Deneb Opteron

It costs quite some money to transform SOI fabs into HK/MG fabs I think... might be a budget issue for AMD

I can post them a few Kilos of Hafnium if they are hard up.

Gota help the little green guys.

Send them some coupons if you have some spare.

I'll start a soup kitchen for the Engineers ... we will put numeric soup on the menu ... none of that alphabet soup rubbish.

Hector has probably had them doing 20 hr days since the stuffups early on with Phenom.

Don't be surprised if we have to treat some of them for mange.

Some of them might need some vitamin shots too I imagine ... any Vets out there with a trank gun??

I hear a couple have already gone rogue and are barking at the moon and hiding in the back of the litho rooms ... in the dark.

Poor guys ... Hector probably cut 30% of their pay because they will be producing smaller chips on 45nm.

We could start a support group for the Deneb Survivors !!!
