Welcome to the team VB!

The X4 620 certainly is a stonking processor for the money, though my hunch is that the OC limitation lies with the motherboard. 250HTT can often be a real struggle for some boards. It may have been a CPU related limitation if the mobo didn't offer a decremental NB multiplier.

Good work!

Thanks Mul.

It was the most frustrating OC I've ever attempted. Usually you get towards it and gradually strike the balance between stability and the CPUz screengrab of death. This was just all or nothing.

It's amazing value for money though.

Picked one of these up last week actually... Gotta say for the cash it is a complete bargain. I managed 3.4Ghz but unstable. Running at 3.2GHz very stable

At £70-80 for a 3.2GHz Quad CPU you can't complain at all

Nice review VB

Great review VB.

I think I'm alone in feeling uneasy about the pricing on this.

I do accept that, yes it's quad core, and yes it'll capably handle what's thrown at it - and I can see oc'ers liking this.

So why the uneasy feeling... perhaps if the £77 is mrrp and it onlines at £70 or a snatch under, I'd feel a little better.

But I think I latch onto the superpi score (which there is a multicore version available now I think I've seen), just under 25s for an oc. Then look over at Intel's camp, especially considering the £220 mobo/cpu idea. Intel are ofc making the adjustments too, and they're 'pentiumizing' previous c2d cpus, and yeah they're 2 cores (if u bank on 4 cores, or have a legit reason to think ur software will use it - ur not really on a budget imo) - but they are more attractively priced imo, and ofc they oc too.

Tough one.

Very good review, and looks like the chip is going to be a bit of a bargain, to check if the 250fsb is the limit did you drop the multiplier down?, this may give an indicator if the 250fsb is the problem or the 3.2ghz clock is the limit

Hi, new here.

1. Nice review, man. 'Cause that's real life, where the silicon you buy does only a part of what most reviews say.

2. It looks to me that the notorius and long praised 785G chipset is somewhat stucked in OC. I don't especially blame a certain producer, but the chipset/BIOS combination. AMD770 + SB710 appears more OC-friendly, since I personally jumped over the 250 mark, and I bet I'm not the only.

3. Picked one of these nano-beasts last month. I've come along with a CADAC. After getting around 3.7 GHz with decent voltage, finally managed the 3.9 GHz with 13 x 300 on air cooling, but at 1.6V (see validation below). By the way, was it possible to set the memory to "Ganged" in the BIOS? I've noticed that you may OC further in this way.

It is also a question of luck: during more than a 6-year period, this is only the third CPU I own in a long series which proved to be highly OC-able.

Sorry, I'm not allowed to post links.

Yes. Sorry I thought I'd said. The multiplier was dropped to 5, 7 and 10 and it still fell over at 250. Which does indicate it's probably the mobo.

Another test is in the pipeline.
