USA System Configuration And Overclocking
USA System Configuration
Once the system was up and running, we benchmarked performance without enabling energy-saving features. With some data gathered, it was time to start testing just how we could lower power consumption while maintaining performance. And last, we would explore our ultimate intentions for this system: overclocking with as little increases to voltages as possible.
At stock speeds, we enabled EIST (Enhanced Intel SpeedStep Technology) and CPU Enhanced Halt (C1E) in the BIOS. We next installed Gigabytes Dynamic Energy Saver Advanced utility and found complete stability running the CPU voltage switch at level three, providing the greatest drop in idle VCore. The last attempt to lower consumption within DES failed as we lost stability when turning on the utility's CPU throttling control.
We next turned to Windows Vista’s Power Options explored in this review, and found the balanced setting to be the best option for our system, lowering the watts consumed with barely any loss of performance. Lastly, the Antec Three Hundred’s two case fans were overkill even on low speed so we disconnected the 140 mm fan to shave 1.2 Watts of consumption. After stability testing and running our complete test suite, it was time to move onto overclocking.
Overclocking
The E0-stepping Wolfdale processor did not disappoint, remaining stable at 3.95 GHz with VCore manually set to VID (1.25V), and the CPU fan on auto control. Sticking to this voltage was crucial, as any attempt to lower or raise VCore also disabled SpeedStep’s throttling of CPU voltage. We had no luck utilizing the DES Utility while overclocking, and thus had a bit higher idle VCore versus stock speeds. But fortunately, the system was totally stable without the need to increase any other voltages. It came as a pleasant surprise the G.Skill memory even ran fine at 4-4-4-12 timings at 1.8V, as we figured either timings would need to be relaxed or DIMM voltage bumped up.
Lastly we turned toward getting more performance from the Radeon HD 4850. We didn’t push the Sapphire card to its limits, but instead used AMD's Catalyst Control Center to overclock, so 2D clock speeds would cycle lower. We maxed out the core at 700 MHz, but left the memory down a bit so there was no need to manually increase the GPU fan speed to cool these bare memory chips. Again, using Vista’s Balanced power option setting, we stability tested the system further and then proceeded to run the test suite.
Stay tuned. Once the other three countries participating in this challenge finish introducing their respective $750 systems, we'll publish the benchmark results and winning configuration.

Thanks for the review.

yet again Toms Hardware couldnt be bothered pulling their finger out and converting to Sterling......
SORT IT OUT!!!!!
@ PT88 cant you read? it tells you the source is international & comes from Toms US it's not a Toms UK article.
Are you too lazy to convert it for yourself or something, what a bone idle little world you must live in go sort your own lazy arse out.
+1 for the sterling! I'm beginning to think there's no UK office!
where's the price of the operating system, the review mentions using vista ultimate and if that was priced in it would add another £130 or whatever the dollar equivalent is..
also is a 1TB harddrive really needed, there's no tv tuner card included in the price so the machine isnt destined for a life of tv recording in which case a 500gb would be a better balance imho
this review is just another exercise in overclocking at a price point. easy for the reviewer to do as when the same chip was a top dollar (pound) model he probably wrote a review on overclocking it then too..
How about a euro price? Sterling is hardly worth qouting is it? lol
lol e8500 is 240€ here...
Well, what relevance does a 750 dollar Computing Challenge have to do with a .co.uk site
Whats the point in posting a US article on a UK site, if i want to see a US article, i go to www.tomshardware.com
My gripe is with Tomshardware not being assed to write .co.uk articles. For instance, the hardware in this review where American based prices, the prices the hardware vendors sell this for in the UK will likely be more than in the US
So this article has no relevance to the UK Market, so why post it on the UK site
Tomshardware are just being bone idle, as i said before, SORT IT OUT!!!!!
agree with person above, would it be too hard for the uk team just to get us the ukl prices for that? it would onlyput the article back for a week still a good read
and before people shout at me saying am i just to lazy, (well yea but XD) Uk prices are not the same as euro prices, and they are definatly not the same as us prices (i hear of peeps piking up 9600's for around 50 dolars while over hear they are around 75 quid, big diffence)
UK is RIP off land! please NEWEGG Y wont u ship to uk!
So I have a bit of time to kill, those prices are fairly consitent with the euro price on komplett.ie... so all you english speaking people in euro land dont worry this article translates easily.... (and if i am not mistaken sterling and euro are almost at parity (what with the british economy going down the shitter) so maybe you British people can get these things even cheaper...) some items were slightly changed due to availabiltiy

The UK articles are still to come, did you guys up there read any of the article before posting?
I'd consider an AMD-based rig, on the basis of cost (much less than what you shelled out for that blue chip), and overall energy-consumption. The cost of energy in the UK has sky-rocketed, and an AMD 780-based chipset would be the ideal solution in my opinion, along with a low-power version of the A64x2. The saving might allow for a better graphics card, although those things tend to be over-priced here compared to the US.
Still, hindsight is always easy. Thanks for the article, it gives some good pointers on what components to get from a performance perspective.
p.s. that RAM deal looks fantastic.
Thanks for the great article TomsHardware,
but can you please tell how much watts did the system you built use in default and overclocked settings (especially the E8500 overclocked) when running in 3D mode? I have an 80+ 400watt PSU and I'm hoping to upgrade with an HD4850 and one of the new Phenom II (maybe a 910 2.6ghz) but I'm afraid the PSU won't handle it. Will there be any problems w/out overclocking the system?
Thanks!
I was going to post a long winded rant about THG.co.uk being nothing but a front for THG.com...but whats the point. Bookmark deleted, DNS entry forced to localhost. Never comming back.
BTW, wasn't this place a great source of information BEFORE they added tomshardware.com...
ENGLISH PRICES - we have to pay VAT remember 15% extra cost ( i'd hope all the sites are working at the current 15% vat rate, if they arnt it was 17.5% for people who dont know)

- not shopping around here but aria is ususally alright on price, so i get most from there (links at bottom)
E8500: £139.99 + VAT = £160.99
Arctic Cooling Freezer 7 PRO: £11.95 + VAT = £13.74
Gigabyte GA-EP45-UD3LR: £88.95 + VAT = £102.29
G.SKILL PI Black: 4GB£54.87 + VAT = £63.10
Sapphire 100245L Radeon HD: £106.04 + VAT = £121.95
Western Digital caviar 1tb: £82.83 + VAT = £95.26
Antec Three Hundred: £45.95 + VAT = £52.84
Antec Earthwatts 380: £34.47 + VAT = £39.65
Lite-On IHAS120 20x: £14.77 + VAT = £16.99
TOTAL = £579.82 + VAT = £666.81
i tried to get all components as exact as possible as in the article although the model no on the dvd drive dosn't quite match up.
Admittedly the price would change if you got all the items from one site getting the best bits from them that they offered - it seems ebuyer has gone up in my opinion for stocking alot more stuff than i thought they did
its not super cheap but its still cheaper than alot. its about the kind of money i would spend on a new pc.

400 watt power supply is to low for a modern video card. look into a 630 watt which will not only last you for this build it should supply enough power for 3 years from now when you stumble across a HD 4870 for $50
Never skimp on the power supply as you only really want to buy a new one every 5 years or so.
Got a 700 watt power supply from newegg at Christmas for only $40 after sale price and rebate. think it was a raidmax
As for why the article was not including a AMD cpu? well the lost cost does not make up for the fact that AMD really don't offer much room for overclocking and thus the value is low which is why the cost is low.
Save $30 and purchase a E8400 cpu instead and run it 4.2 ghz and use a smaller hard drive. think WD has a 500 gig for $59
those 2 changes alone account for a $70 reduction and what fool spends $40 for a 380watt power supply? even more room for savings on the psu
this might be a reasonable setup but i agree a E8400 would have been better for its price. and a reasonable powersupply would have been needed something as raptoxx or yellowdragon or xilence would have gotten away perfectly only costing about 40 euro so i agree that you must be a true fool if you spend 40 dollars on a crap 380watt powersupply because these are worthless for 4850 and i can garantee you it wont even boot stable and it would hung and reboot even before you enteret windows. but for the same price you could have an AMD quad core build anyway. sure for some games dual core still preforms awsome but i can garantee you AMD's Phenom would do great in windows 7 based games because of the 64-bit and extensive use of multicore technology. most games are still capped to single or dual core but when you like to do more at the same time quad core is just better, BTW even the Phenom 9950 overclocks good. but for a mere $20 more you get a phenom 920 black edition so dont borther and stick with that if you want a great system in this price range.
When you switch over to an AMD quad core you are raising the cost for the cpu as well as lowering the speed significantly. also you now have to search for a motherboard possibly costing even more.
And lets face it AMD don't over clock all that well which is a major negative factor since they come out of the box a whole lot slower to begin with. The reason for going Intel is that whatever you purchase will run a lot faster once you tweak the settings.
Only one reason to go AMD and performance is not in the equation you go AMD because you really want a shiny new PC but don't care if it runs as slow as 2 year old Intel
