Fastest single core 939?

[Amonlym]

for what its worth, my almost end of run 4800+ (few months old) will push past 2.9ghz, and gets withiin 50mhz of 3000. BUT

op mentioned: shuttle pc, so dont expect big OC, and not much interested in OC. so i dunno how relevant talk about Oc really is.

befor you spend money, see if you can work out more mhz from the opty. if you can get to 2.4 you match the 4000+ 2.6, your matching an FX55....

And... if he gets a 4200+ an overclock to 2.6 should be a relatively simple task. FSB would only have to go from 200mhz to 236mhz which even some of the weakest chipsets will manage. Then he'd pretty much have FX55 performance per core - i know he'd only have 512kb of L2 per core rather than the 1mb the FX has.

It just seems to me he'd want to stick with the shuttle which means staying socket 939. Dual core would bring far more benefits than a faster single core in all honesty.

When i moved from a 3700+ @ 2.6 to a 3800+X2 @ 2.6 my DVD encoding time was literally cut in half... plus windows was lightning fast when i was doing it. In the past while encoding it would nearly crash the PC if i attempted to browse with explorer. With the X2 i could do 3 or 4 things and it would remain stable and rapid.

Being the original poster I'll probably move up to a X24200+ given the price as the oc is not going overly well. The chip used to do 2.3Ghz with no pushing in my last system but this is definately topping out at 2.2Ghz

I found a review to prove it and some bios option shots

Overclocking
For our overclocking tests, we swapped out our Corsair 1GB DIMMs for a pair of 512MB OCZ Platinum Rev 2 memory modules. These particular DIMMs use Samsung TCCD chips and have proven to be solid overclockers in the past, making them perfect fodder for this round of tests.

As usual, we began our overclocking testing by dropping the CPU and HyperTransport processor link multipliers and raising memory timings to 2.5-4-4-8 with a 1T command rate. Then we started turning up the HT clock, easily making it up to 220MHz with no complaint. But the SN21G5 would go no further. The system wouldn't post with a 225MHz HT clock, and no amount of voltage or memory timing tweaking helped. We also tried lowering the memory bus speed, but that didn't work. Neither did swapping in different DIMMs.

Small form factor systems have never been particularly adept overclockers, so the SN21G5's 20MHz HT overclock isn't that surprising. To its credit, the system was rock solid with a 220MHz HT clock. To see how much performance an extra 20MHz could buy, we upped the CPU multiplier to 11 and ran a few tests. Memory timings were set to 2.5-4-4-8-1T for both the stock and overclocked configs.

So it seems I reached the max and stopped

Yeah, the 4200+ would seem to be your best bet - or a 4600+ if you can track one down for a great price!

With that 220mhz fsb you'd see either 2.42ghz or 2.64ghz respectively which would be more than acceptable.

You can get faster single core cpus then X2s,,, and plus there not that meny games that takes advantage of dual core atm. So a amd X2 running a single core game will be quite pants

Lilke my 28month old [email protected] will thrash any 939 X2 core cpu for none dual core games.

Still holding onto his 2.76ghz socket 754 hammer :O Must be getting close to 3 year old too. Longest CPU i have ever owned ^_^. Mobo is now PCI-e, ram has doubled, GFX has been upgraded twice but the same old cpu is still chugging along .

You continue to think like that. I can each 2.7ghz on my 4400x2.

Quake 4, Oblivion, Supreme Commander, COD 2, AOE 3 are all dual core supported games.

I guess you didn't read review comparing Supreme Commander on single core and dual core CPU's I guess?

I'm in a similar situation, so thought I'd post in here instead of creating a new post.

I've currently got an Opty 146 running at FX57 speeds. That's been lovely, but now I'm doing a lot of HD video encoding. Movies are only taking about 5 hours or so, but during that time the fans are hitting full wack and the machine's generaly not really usable for anything other than posting this and messing on the net. Would I benefit from getting a x2 3800? I've seen one 2nd hanf for under £50 so tempted to give it a wirl. Not sure I can be bothered with the overclocking, though might have to give it a go if the bug bites again.

Any thoughts? I'm assuming I could either run one core for the encoding and use the other for a game of FMmmmm2007, or use both cores and just half the encode time?

EDIT: Should add I don't game (that's what the 360 and Ps3 are for!) so not bothered about that.

 

[squiffy]

Just to say my 3700+ is a slug totally unusable whenever I'm doing encoding. X2 still is fine and can play games.

You don't need to apply CPU affinity rules, the OS does it for you. Although if you're doing several things at once might want to adjust priority. You can't expect to encode 2x100% and still to be fast, even if you have quad core if you've maxxed all cores out it'll still be dog slow.

Get the dual core, you won't regret it.

Windows itself uses multi-cores, in fact for Windows it makes sense to have dual core, if you're a heavy user. In the past I've encoded music & DVD's at the same time with little slowdown per application or in windows. Forget doing that on a single core

Does the OS handle it if your running 32bit Windows?

(Got a X2 4200+ on order btw)

[squiffy]

Yes, you just need AMD CPU driver. I've installed the MS hotfix, but not the AMD optimizer. Sig machine is running XP Pro 32bit.

Is the driver this one -

AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (x86 and x64 exe) 1.3.2.16

Miles down the page? (terrible layout in my opinion !)

yeah that's the one.

So you reckon it's worth the £50 ? Will I need to OC it in order for it to feel as fast as this opty in normal use? It's just odd going down in clock-speed and cache that's all

 

[squiffy]

Yup definitly worth it, I don't think majority of people are "power users" so aren't wowed the improvement in dual core. Most people don't have two instances of EAC open, rip & encode from two optical drives, to two different hard drives...all at the same time.

Just to confirm what has already been said - you don't want an FX57. When I got mine on launch day the only alternative was the 4800+ and there was no good overclocking RAM available in a 2GB set. So i either would have to settle for lower clock speed (Stock 4800+) or 2T (Use 4 512MB sticks and oc). I wasn't happy with either option so I decided to go for the FX57. Its still a good CPU, it handles games well etc. but to be honest it isn't a good decision. 2 years ago (Well, 23 months) it made some vague sense because I wanted the best gaming system, but now if you were thinking of buying a processor I would definitely say go dual core.

You end up feeling unable to justify having slower multitasking just for a few extra FPS in games if you buy a single core CPU.

Well mine showed up this morning and I haven't fitted it yet so thought I'd share the stepping

Chippie reads -

ADA4200DAA5CD
LCBKE 0643TPMW
Y974284K60886

Thought it might mean something to someone.

From another post:

"CPU info for mine is:-
ADA4200DAA5CD
LCBKE 0643TPMW
Y974284K60123

I've settled for 3.03Ghz @ 1.45V (275 * 11). It did superpi at 3.15, but not orthos"

that is a damn site better than my 4800+ LCB9E

yours is an idential stepping....

Nice one Whoop.

Your overclock won't be held back by that chip then!

Great find Amonlym!

Cool

From my bios screenies what should I really be changing ? There are 5 HT options and I know nothing on this bios just my old one


Whoop

 

[Amonlym]

at a guess, ht setting to 800mhz / 4x multi / 4:1.

then wind up fsb till shes unstable.

then try 600mhz / 3x multi / 3:1

see if it goes any further. if not go abck to 4, and drop a few mhz fsb for stability
