Hardware 22 - The Second Day Magazine

Posted on 23rd Apr 2011 at 09:52 by Podcast with 7 comments

Podcast
It’s podcast time again, and this time we’re talking about all the lovely hardware we’ve seen in our labs over the last few weeks. Clive starts off by telling us all about the AMD Radeon HD 6790, and why it’s only likely to be around for a relatively short period of time.

We also get chance to quiz Antony on the Silverstone TJ11, which it was his pleasure to review. The case is humungous, but isn’t quite the water-cooling behemoth we expected. Paul then gives us an account of his recent trip to Istanbul to cover the MSI Master Overclocking Arena European finals. Extreme overclocking and benchmarking is a funny old world, and it’s always interesting to get to see the action first hand.

Sandy Bridge overclocks to 5.2GHz?

Posted on 1st Oct 2010 at 12:36 by Richard Swinburne with 31 comments

Richard Swinburne
Facebook is occasionally a wonderful thing. Gigabyte employee and extreme performance guru, Hi Cookie, posted a rather interesting and cryptic message today on the book of faces, claiming,

'Air cooling 4C/8T 3Dmark vantage Pass by 5.2GHz, hmm...interesting ^^'

The replies immediately alluded to and assumed Intel Sandy Bridge CPUs, as a "SuperPi sub 7 on air" would smash the current world leader on HWBot.

At this stage it's worth noting that nothing has been confirmed by Gigabyte, the Facebook post merely states that something has been overclocked to 5.2GHz and that it rips through SuperPi.

However, given that the GO OC competition is over and Gigabyte, like other motherboard companies, will be beavering away at optimising their LGA1155 motherboards ready for launch, things do certainly point in the Sandy Bridge direction.

Feel free to see the thread below, and chirp in with your own thoughts on the forums.

ECS P55H-AK Overclocking

Posted on 26th Sep 2010 at 10:12 by Richard Swinburne with 4 comments

We heard a surprise rumbling from the direction of ECS recently, from its P55H-AK. With a new and rather tasty aesthetic design, and the promise of hitting 5GHz with a K-series CPU got us wondering if ECS had made a board that was.. well, worth buying.

At $300 (it's not yet available in the UK) out of the starting blocks there's already a hefty weight on it for a P55 board, even if it does have extra NF200 and PLX chips to add more PCI Express lanes.

Unperturbed, we still wanted to have a gander at its overclocking capabilities, so we requested a board for a quick test. Once we had it in our mitts we dropped it on the review block (it's a cold piece of granite that bares the scars of previous torture), with a Core i5-750, some 2,200MHz Elpida Hyper and a Titan Fenrir.

What happens if Intel does end overclocking?

Posted on 29th Jul 2010 at 12:42 by Richard Swinburne with 79 comments

Richard Swinburne
I've taken to the armchair looking out over the veranda, scratching my wispy beard while sipping an ice tea. I've pondered long and hard about the consequences of the overclocking restrictions Intel apparently plans for its upcoming mainstream Sandy Bridge CPUs.

The feedback in our news post mirrored my own initial reaction: how dare Intel! How dare they stop us from generating £700 CPU performance from a £150 one?

Hardware 13 - A Case of the Uglies

Posted on 28th Jul 2010 at 13:33 by Podcast with 8 comments

Podcast
Welcome one and all to Episode 13 of the bit-tech and Custom PC hardware podcast.

As befits the summer, this episode is a loud, effects laden blockbuster, where the team talk about Intel's K-series overclocking CPUs and the rumours about Sandy Bridge's lack of overclocking.

Antony and James explain our updated case testing methods, and we cast an eye over Cooler Master's HAF X and the Antec Dark Fleet.

Will mini-ITX lead to disappointment?

Posted on 27th May 2010 at 11:37 by Richard Swinburne with 32 comments

Richard Swinburne
If you've been reading the site recently, you've probably noticed the real resurgence of mini-ITX mortherboards. We've got Intel to thank for that since it's pushing the form factor hard this year - all these new mini-ITX boards are made for its Core i3 and i5 CPus with integrated graphics.

However, mini-ITX has been a real backwater until now, which means that many of the companies are exploring unknown territory.

AMD 890FX overclocking and memory performance

Posted on 27th Apr 2010 at 12:26 by Richard Swinburne with 3 comments

Today sees the launch of a new six-core consumer CPU from AMD, the Phenom II X6 1090T Black Edition, and new high-end motherboard chipset, the 890FX.

As you'd expect from a big launch, there's been a lot of jostling for position behind the scenes, especially here in Taipei, Taiwan. As it's a high-end launch, the various motherboard and memory companies involved have been checking out how the new chip and chipset fare with overclocking, and I dropped by G.Skill's offices a couple of weeks ago to get their impressions of AMD's new kit.

At the time, I filed a story about G.Skill's latest 2,500MHz DDR3 but I also had the chance to see the Asus M4A89GTO Pro (890FX/SB850) running four sticks of DDR3 at 1,800MHz, with timings of 6-8-6-24-40-2T.

The overclocked test system used the latest Phenom II X4 965 Black Edition C3, however we also saw it achieve similar memory speeds using a Phenom II X2 555 Black Edition too. The higher frequency is easier to hit with the latest C3 stepping CPUs thanks to AMD’s refinement of its CPU-NB link, but if you have a “good” C2 it can hits these speeds too.

G.Skill were keen to point out that the CAS 6 isn't achievable with every 890FX board at launch, although when as I visited a couple of weeks before the launch, the company's reps told me the FAE teams at each motherboard company still had time to tweak and tune their BIOSes.

4GB memory kits will be available soon and should have either Perfect Storm or Trident heatsinks attached, but the company is as yet undecided about upcoming ranges. As for buying an Asus M4A89GTO Pro - well, when AMD launches its 890FX soon, then you can get one! Let me know your thoughts in the comments.

The Problem with Overclocking

Posted on 21st Dec 2009 at 10:50 by Clive Webster with 20 comments

Clive Webster
For some completely unknown reason (alright, just one I can’t tell you yet), I’ve spent most of last week testing and overclocking CPUs. Because of the way the magazine deadlines work in the run-up to Christmas, deadlines are tight, but the urge to get the very last MHz from a CPU still bit me pretty hard.

Budget overclocking is back!

Posted on 30th Nov 2009 at 10:50 by Antony Leather with 25 comments

I’ve felt a little lost over the last six months or so. AMD still hasn’t come back with a definitive answer to Intel's Core i7 and Core i5 CPUs and even they have been prohibitively expensive for many looking to upgrade from a Core 2 system.

Gone, it seems, are the days of the Core 2 Duo E1200 which could be bagged for less than £40. After a 100% overclock, it could turn into something that gave £150 CPUs a run for their money. I've used the CPU in several systems that I've built for people over the last few years, coupled one of the many budget uberclocking LGA775 boards that were pushed off the production lines.

Gigabyte TweaKING OC Event: European Final

Posted on 3rd Nov 2009 at 14:55 by Richard Swinburne with 2 comments

Gigabyte TweaKING OC Event

European Final

Manufacturer: Gigabyte

Gigabyte are well known for its overclocking events: the Gigabyte Open Overclocking Championship (GO OC) ran earlier this year and encouraged competitors to overclock their Core i7 CPUs using any means possible, and ran Super Pi 8M and 3DMark 06 for the best scores.

The TweaKING event in Paris is the European leg of this new style of OC tournament. Less emphasis is placed on the quality of CPU and more is placed on the ability of the teams to tweak the memory and motherboard. How? The CPU frequency is capped at 4GHz, meaning the teams had to crank the memory and baseclock on their Lynnfield i5-750 CPUs up as high as possible to achieve the best result.

This still puts an emphasis on CPU quality to some degree, but its also brings the motherboard back into play more, which is an angle Gigabyte obviously wants to push. There was no limitation on the OS tweaks allowed too; so WinXP hacks a plenty were rolled out: services were neutered, registry was copiously tweaked and anything deemed excess was cut off.

However, every team had a standard set of hardware to use: nothing extra was allowed, not even an additional fan. Even screwdrivers were provided!
