RIGHT LADS...

Im getting a littl ebored with this 3700+ SD, its a cracking cpu but Ive had it since they came out and fancy a change. I dont really fancy an FX57 as I dont have phase anymore but the whole X2 thing is making me want one of those.

I would only want the 4400+ or the 4800+, as I want the Cache... however my RAM wont do much over 260mhz atm so Im hoping that the 4800+ will be a better option. I Would love 3ghz you see... maybe im asking too much?

I have a HE120.3, AQZ pump, Storm G4 and a Silverprop HL on the 7800gtx, so my watercooling is pretty good, but is 3ghz gonna happen with the 4800+?

I have found the 4800+ for £500 on ebay (brand new).. so I thought this might be a good choice.

I mostly play games but obviously use the PC for bittorrents, surfing, playing music etc so is the X2 gonna be good... I hope so?!

Someone help pointing me in the right direction... should I be waiting or getting on the X2 funbus?

PS... i normally run my SD at 2.8ghz so you get an idea of what im coming from. :)

Thanx for the help!
 
I think the 4800 X2 is a good move mate - its cheaper than the 57 by a hundred notes or so (retail). I cant see why 3ghz would be impossible with that setup.
 
Indeed. Fast and Furious. The 3800 X2 I use in the Tempest hits 2.9ghz. Its a fantastic overclock for a dually. I've no idea what you can achieve on air/water, but I think they're worth every penny. Good for benchmarks and gaming!
 
Okay talking form experience here - watercooling is good for duallies and the right choice for you to make would be the 4800 as it runs cooler at higher clocks than the 4400 (because it needs less volts), this is important for overclocking.

The max multiplier is x12 and I can get 261 using mach2 with R507 conversion.

On water cooling though (and you need at tleast a dual 120mm radiator) probs 250mhz is more appropriate (3Ghz as Phil said) - which is the most you can achieve at stock voltages.

For better heat control and if you do not mind voiding your warranty then get warlord shigs (here on EPUK forums) to take the IHS off - this will help with the cooling especially under load.

Not sure about a fully overclocked GTX too. most people use a separate cooling sytem for that utilising a single 120mm rad. Dave barker and nick25 have better experiences in that area, I would not be comfortable running both of 1 loop fully overclocked 24/7.

The new series Thermochill rads offer a 20% better cooling so it might be worth considering a change if you want to stay single loop?

be easier to just get a mach, and stick the 7800 on the water loop with a pelt. Thats what i pretty much did

Add a water chiller and have it all on the one loop keep it all under 20 degrees

Too right mate - water chiller is a superb option as it also allows for higher FSB than those that would be achieved under phase.

Having tested one - I can whole heartedly recommend it as a great way to fully supercool a system.

Just a quick question. What would be better for such a setup as I'm probably interested in something similar:

a) one triple rad for x2 and dual 7800GTXes:

res --> pump --> cpu --> GPU1 --> GPU2 --> triple rad --> res

b) One double rad for X2 and a single pa160 or 120mm.1 rad for the GPUS. but one pump only:

res -> pump -> cpu -> single rad --> GPU1 --> GPU2 --> double rad --> reservoir
 
On a single loop with a Thermochill 120.3, 1/2" tubing, AQZ 50Z, Storm G5 cooling my X2 4800 and a DD GPU block cooling an Ati 850XTPE, my best overclock was just over 2.9Ghz that was stable for the CustomPC benchies giving me a score of 1.72. Temps were around 34degC idle and maxed out using dual prime95 at 57degC when using vCore 1.55v - 1.58v to achieve the 2.9Ghz. Temps were high but if I ran vCore at 1.5v the temps never climbed past 48degC giving me 2.8+Ghz. I don't think my chip is the best clocking 4800 out there so you might be lucky and get 3Ghz but I am not sure how stable that will be i.e. whether ur aiming to bench at that speed or want 24/7 stability. Running my Mach II GT with the same mobo, PSU and X2 4800 I have it prime stable at 2.9+Ghz and generally usable at 3Ghz.

Hope that helps
 
*** a bit off topic really, but :

I'm not a bencher - I have never run a benchmark except for Custom PC once for an article I got to do.

All I want to do is play games at top speed with fast GPUs and a very fast CPU stably for quite a few hours at a time when I'm on hols or at a lan party. I also want it to be quiet so I don't notice it whilst playing.

I have to admit, I'm not sold on SLI really as i think its not the way companies should go but what the hey.

Basically, what I was planning was something similar to the Storm SLI but with a Black Ice Xflow Xtreme III on the top panel of a v1100b case rather than the pc75. However it has to fit a TV card and sound card in the top slots (hence an asus sli premium board or that dfi expert one).

I guess for block all i would change is the LRWW block to the swiftech storm G5 and not worry about the G7.

57C is very high though when stressed right out especially if i would have dual SLI cards in there.

Sounds good - although if benching is not your thing either a single Radeon X1800Xt or 7800GTX will serve your needs, probs best to choose the one that runs cooler for the purpose of your choice..

1 card and 1 CPU should yield some great results - if you just want good (not stellar) performance go for a new opteron 144 or 146 (great bang per buck). A 3x120mm rad system such as the new Thermochill PA series would be enough to cool your system a treat.

57degrees is not bad, the stock cooler will do that at stock speeds - you'll just get the opportunity to reach those temps with some excellent performance.............. no one says it has to be 24/7.

Remember San Diego 4000 cpu or FX57 running at stock are used on todays review test rigs to compare performance - have a quicker speed does have positive impact but using either of the above cards and following the reviews we see out there now means you achieve 1600x1200 goodness with all the bells and whistles on running a cpu of that caliber at stock (2.4 or 2.6Ghz).

Meaning to enjoy gaming at it's best you only really need to clock as high as possible at stock volts to yield great results at stock volts and lower temps than a volt adjusted overclock (normally up to 240Mhz on stock voltages = 2.8Ghz or 3.1Ghz respectively on the above two units) - the temps will be somewhat less than 57degrees then.
 
This post is really aimed at Chris - reference my choice of the PC75 for the Storm SLI. The new range of V series cases are very nice indeed, but they are no good for extreme watercooling, plus they are incredibly difficult to anodise due to the way they are designed. The 75 is still one of the best cases for watercooling, especially when it comes to using a decent triple rad - the PA120.3 is now the best pc rad on the market, and with shroud and quiet fans installed, can run the system virtually silent. I still think its a good choice!
 
Thanks for the info Phil - so a triple rad won't fit? I know that a certain firm called V**d** use a v1000 in their dual core system.

The top of the v1100 is 550*210mm. and the pa160 is 430x128. admittedly, with a depth of 68mm+shroud+25mm fans, that's 9cm. So for the PCI cards that leaves 11cm from the rad to the top PCI slot (enough for sound I think), but the question becomes how many 5.25" drives do I lose (3 with tubing probably) - but that's ok becuase a fan controller is thin enough and the floppy is small so all I need is room for a dvd drive.

don't worry about anodising I don't really want that, but the pc75 is just sooo huge. I know i'm being a bit stubborn but i really didn't want a massive case - so maybe a dual rad on top and a single 120mm one......I don't suppose an admin could just split from my post on and make a new topic? thanks.
 
And you are sure a triple won't fit lol? So what would be the loss in going to the xflow III that might fit over the pa120.3? These are new rads and I haven't found any reviews yet. I realise that the pc75 would be ideal for you, but it is just so tall and I love the v1100 in comparison. gaaaah. why so difficult :P

Although, I guess if i went for non-sli with a nf4 ultra board then it would all fit snuggly?
 
Where u put the PC may influence your decision, since I put my PC75 down on the floor next to my desk where the extra few inches of depth and height are more proportional to my desk. I always thought that the mid sized cases I had there previously looked a little dwarfed by the desk although this is very subjective I know. Plus the PC75 case, as Phil points out, is very functional allowing a triple rad and extra width making the watercooling 1/2" or 7/16" tubing much simpler to plumb in kink free. Space vs aesthetics ...
