Well the time for waterblocks is almost upon us, anyone excited?

Expecting them to be quite expensive, the blocks are as big as some dual chip blocks

Was it today or tomorrow they're due?

pgi947 · 26 Jul 2012 at 13:57

Tomorrow the 27th, at this rate I'll have the waterblock before a functioning machine

As for prices, I say £90

pgi947 · 26 Jul 2012 at 17:40

Yeah I'm thinking in that region too.

Do we know when OcUK will be stocking these? I am waiting on the blocks as the LAST piece in my TJ07 rebuild!

Hi,

If anyone is interested I was having troubles with my 7970 artifacting on desktop and stuttering gfx,sound in games, I think it was when CPU turbo kicking in which was at 4.6ghz and once I set to default it was ok, Simon D suggested it was my PSU not being powerful enough 550w, so I got a new 850w and re done everything and now the overclock is fine and everything works, although I still had the artifacting problem, but once I disabled Lucidlogix Virtu MVP it went away.

I also relised that at the sametime I put in the 7970 I also put 16gb of new ram with the old overclock on the ram, I am not sure if you swap the ram it sets back to default or not, but anyway awesome card.

pgi947 · 27 Jul 2012 at 06:25

The most I could get out of rjk was that ocuk will be stocking them and should be on the next ek order. This could mean they have stock or waiting for it too arrive.

Someone want to pop into cs and ask?

@whizz, glad you got it sorted

Nickolp1974 · 27 Jul 2012 at 07:52

So whilst waiting for these blocks could people please post there ASIC quality and max core clock please, still trying to determine if i have a problem. Using this info as a refererance only.

Lightning 7970 only
Mine

67.5% and 1207

pgi947 · 27 Jul 2012 at 08:58

Off the top of my head 62.4% 1300mhz and haven't touched max voltage yet.

Water should in theory let us use lower volts on higher clocks, aiming for 1350/1800.

Thx, i know your the first and i need more results but in theory shouldn't i get a similar clock to you?? Or maybe touch higher, due too in theory, less leakage

Oh had another quick blast with ln2 yesterday, i altered the graphics drivers time delay Before crashing in the registry, had the bare minimum processors running, And still only got to 1207, and when it does crash it wont boot in ln2 mode, last time had to do a fresh windows install to get it working again

pgi947 · 27 Jul 2012 at 09:18

Don't bother with ln2 mode, its only of any use if you are using extreme cooling and have the custom version of afterburner extreme to push the voltage above 1.35v.

Normal bios, fully unlock afterburner will give you clock limits you will never reach with 1.35/1.7v voltage caps with 20% powertune and +30mv aux power.

As for clocks its system subjective imo. PSU's will need to be beefy and using a decent motherboard, for example my ud7 has optional power inputs to provide extra power to the pci lanes, I think little factors like this can help.

Wouldnt normally bother with ln2 bios but been off work for 5 days and was bored!

and i take your point reguarding system specs, just need to save a little more yet, my upgrade itch really needs to be scratched at the mo!!

pgi947 · 27 Jul 2012 at 10:11

Scratch it!!!

Been scratching my itch for a few weeks now, next thing is another two lightnings

LOL dont you need a working PC first!!??

just waiting for next job too start first, then i will have about 2k to blow

pgi947 · 27 Jul 2012 at 11:45

Tri fire for 1080p 120Hz no less. Futureproofing for a higher res monitor before I get slated.

I do need a working pc, next week, I hope :rolleyes:

fair enough

7970 xfire is not enough for 3 monitors 120FPS on high settings in a lot of games

Are the blocks supposed top be out for preorder today?

pgi947 · 27 Jul 2012 at 14:11

I'm sure ek's words were something like the first batch available to purchase from the 27th July. Can't see anything on ocuk or ek yet though.
