hd 5850 bottleneck?

[CAT-THE-FIFTH]

The two slots negotiate to x8 / x8 in crossfire mode, but since they're PCIe 2.0 that's still plenty of bandwidth

I'd got for this 4GB Kingston HyperX Kit - it's got low latency (i.e. it takes less time for the system to access it) and it's matched for better performance in dual channel modes.

I think you can do that, but it wasn't what I was suggesting... I was suggesting that, rather than sell your mate the whole of your existing system, sell him the system but with a new, lower-spec graphics card like a HD4770. You then keep the 5770 to put into your new AM3 system, giving you the choice of buying a second 5770 later to run in crossfire. Or do you already have a spare graphics card that you'll be selling to your mate?

The HD5770 is a 800 stream processor DX11 part whereas the HD4770 is 640 stream processor DX10.1 part so it is not possible to use both cards in a crossfire configuration.

TBH,I would stick with what you have ATM as the Q6600 is still a decent CPU though.

OTH,if you want to go the AMD way I would suggest getting an X2 545. It has the potential to be unlocked to a quad core and even as a dual core has 6MB of L3 cache which is useful for gaming purposes.

Also you may want to consider this motherboard for under £50:

It has got a good review although it only has 4+1 phase power regulation:

This motherboard is also very good value for money, if you do not need Crossfire, and it also has 8+2 power regulation:

http://www.scan.co.uk/Products/GIGAB...770T-UD3P-MOBO

nah this mobo is better and its cheaper than the gigabyte one and it has 8+2 phase power (btw wots all this phase power thing)

https://www.pricelover.com/search/?s...IBAC0-G0EAY0KZ

ill go with cpu and upgrade it in 6-12months

https://www.pricelover.com/search/?s...=ADX425WFGIBOX

and should i get this memory

https://www.pricelover.com/product/4...1600C9D3K2_4G/

or this

The Gigabyte motherboard is a better since it uses the 770 chipset as opposed to the 785G in the Asus which means lower performance and overclocking ability. The 785G has integrated graphics which also means increased power consumption for the motherboard too.

The Gigbabyte motherboard has got multiple good reviews and is has performance and overclocking ability near to that of the 790 series chipsets:

Also 8+2 phase power is important if you are going for a 125W or 140W TDP Phenom especially if you want to overclock.

The Corsair RAM I linked too has been used by others on Hexus with 770 and 790 series motherboards and seems to do the job well.

i can just switch off the IGP on the 785g, isnt the 770 older than the 785g anyways?btw theres also loads of good reviews for the 785g evo mobo......im having big dilema deciding between which cpu i should get

dont worry i aint giving him my hd 5770 im gona get him the cheapest gpu i can lay my hands on which hopefully would be for abt £10

They both use the same SB710 southbridge but the integrated graphics does hamper the overclocking ability of 785G from what I have read. Most reviews of the EVO motherboard concentrate on its use as a media board not as a performance board. The 770 chipset is the budget version of the 790X and 790FX chipsets with the SB710 southbridge and no Crossfire. OTH,if you are only doing a smaller overclock and are core unlocking too the 785G should be fine. You might want to look at the X2 545 which lacks the unlocked multiplier of the X2 550 and is clocked 100mhz less too.

oh good then so the 770 can unlock cores?

but the gigabyte 770 is more expensive than the 785g can u not suggest another good overclocking one?

i found this one though

or this one

btw can u attach am2 coolers on am3 socket?

The 785G also can unlock cores. The 770 based motherboard also looks good for the money although I cannot see many reviews for it so I cannot say how good for overclocking it will be. If cost is an issue than the EVO should be still a reasonable overclocker though and AFAIK for unlocking should work fine.

I linked to a review of the MSI motherboard in an earlier reply in this thread and it is very good for the money,although, the enhanced 8+1 power regulation in the Asus and Gigabyte motherboards is better for overclocking purposes and if you intend to plonk in a higher end quad core in the future if it has a 125W or 140W TDP.

Regarding the cooler I would have a check on Google to make sure.

btw is ddr 3 much better than ddr 2@800mhz

and would an athlon II 240 with ddr2@800mhz bottleneck an hd5770?

[CAT-THE-FIFTH]

At 800mhz DDR2 is better but DDR3 has more future potential as it can reach higher speeds.

This article will be useful:

http://www.tomshardware.com/reviews/...ddr3,2319.html

IMHO,an HD5770 should be OK with an X2 240 but and X2 545 would be a better choice as it is faster in games due to the L3 cache it has.

If you intend to stick with only a few months I suppose it might be worth getting the X2 240 over the X2 545 as long as you overclock the X2 240 a bit.

Here is a review of the X2 240 which compares it with other CPUs:

ill oc the max out of the 240 + it runs cool tht should be good btw can am2 cooler work on am2+/am3 socket?, the good thing is tht if i get the 240 ill earn £150 since ill only spend half of my friends £300 which ill save up to buy a better cpu later on

[CAT-THE-FIFTH]

This thread should help regarding the cooler:

http://forums.hexus.net/chassis-syst...oler-work.html

The X2 240 if overclocked to 3ghz+ should still do the job until you can get a newer chip. IIRC there is a newer C3 stepping coming out soon which should help bring the TDPs of the Phenom II chips down a bit.

ok thanks for the info u helped alot

[Blaineoliver]

I would say go for the gigabyte 790XT, brilliant mobo, and it does x8 x8 crossfire, not x16 x4 or whatever the lesser models do.

believe me i aint gona cf.....it uses too much electricty

btw can u unlock the l3 cach and a 4th core on the athlon II 435 x3?

The Athlon II X3 does not have L3 cache as it is based on a different core to the Phenom II processors. Early Athlon II X4 processors were based on the Phenom II but more or less all of them will be based on the same core as the Athon II X3.

The Athlon II X3 and X4 also contain half the L2 cache of the Athlon II X2 and are hence slower in single threaded operations. TBH, if you do intend to get a better processor stick with the Athlon II X2 240 for the time being.

If you were not getting DDR3 and were sticking with DDR2 I would check this thread too:

see if i was to upgrade to a c3 stepping cpu in the future would i need ddr3 or would it work with ddr2 aswell?

tht 5000+ is very hard to find on sale plus its abt £45-50 so it aint worth it
