Another RAM question

[GunRunner]

Hi

Just asking for opinions here!

I am currenty using the 2 x 1gb RAM see here..

http://www.overclockers.co.uk/showp... Latency DDR2 Dual Channel Kit (GX22GB6400UDC)

I am using it in an EVGA 780i with a an e8400 wolfdale overclocked at 4.1ghz (9x455.5). I used to run the RAM (2.1v)at 800mhz because if I used the tight timings of 4,4,4,12 and overclocked to get synchronisation at 911mhz I would get RAM errors testing using prime95. This error still happened but a lot less often if I raised the MCP voltage a small amount, and the RAM to 2.3v. I have now dropped the northbridge MCP voltage and the RAM voltage back to stock (2.1v), and have slackened the timings to 5,5,5,18 and overclocked to 911mhz, and it runs all day without errors.

I am currently running XP with the latest Service Pack and I am considering setting up a second hard drive using Vista 64 and will be looking to use 4GB RAM. My dilemma and this is where I am asking for opinions, is whether I purchase a further 2GB of the same GeIL RAM, or sell it and purchase 2 X 2GB of the following:

http://www.overclockers.co.uk/showp...al Channel Platinum Series DDR2 (OCZ2P10664GK)

I have it in my mind that the above RAM although it has timings at 1066mhz of 5-5-5-18, that I can run it at tighter timings of 4,4,4,12 at the lower 911mhz that I am currently running at. There is also the added benefit of Windows XP seeing up to 3.5gb of the new 4gb RAM. Does this make sense?

PS. I have quoted the GeIL 2 x 2GB RAM kit, however, there may be a better kit that will allow the tighter timings at 911mhz. Anybody know if there is?

Thoughts anybody please?

I will rephrase my questions!

1. If I purchase 2 x 2GB 1066mhz RAM that has timings of 5-5-5-18, and run it at 911Mhz, will it run at tighter timings such as 4-4-4-12? Has anyone any experience at doing this?

2. Should I forget buying 2 x 2GB RAM and just purchase an identical 2 x 1GB GeIL RAM 800 Mhz kit? My aim is to have a dual boot XP and Vista 64 systems, so I need to have 4GB RAM installed to make full use of Vista 64.

1) It will run at tighter timings @ 911mhz, tho I can't say if it'll do 4-4-4-12.

2) I've no idea how well 780i runs 4 sticks, so I'd recommend selling your current memory and getting a 2x2gb kit.

You've quoted the OCZ 2x2gb kit, not a Geil kit. Tho the OCZ kit is just as good as any.

oooops my bad!

Having asked the question about the RAM being run at 911MHz (in synchronisation), is there anythiing to be gained or lost if 1066mhz RAM is run at its default speed (not synchronised)?

Gains would be very small, if anything at all.
