FSB:DRAM???

[bharatwaja]

I dont understand this concept totally...
I will be using the QX9650 and DDR2 1066 Mhz...Maximus formula Mobo

1. Will the BIOS automatically work up the optimal settings?

2. QX9650 says (333 X 9) so the FSB is 333 or 1333??? so my DRAM freq. should be greater or equal to 333?

3. also, for DDR2 800 Mhz, the actualy DRAM is 800 / 2 because its DDR2??

4. I will be buying the Maximus Formula board... So with ddr2 1066, can i make my own CL timings? i.e to get best performance? also should ram also be OC'd in steps?

5. How to test the stability of a particular ram setting?

6. What is the FSB of QX9650? 1333 MHz it says... but CPU-Z shows bus speed of 333 at default... for Ratios, should i consider the bus speedRAM or FSBRAM???

Anyhelp is very much appreciated

You have money to burn huh? $1k cpu, $300 mobo & not a clue what your doing. Did you happen to pick up a nice HSF along this journey? I don't think I want to know how much you spent on your memory.
1.) Yes (optimal being not overclocked, running stock. So probley not the optimal your looking for [which im guessing is overclocked to the maximus w/ no effort on your part]). With default settings your DRAM will be >333 (DDR667).
2.) FSB is 333. 1333/4=333. Intel chips quad-pump the FSB, AMD double-pump. Your DRAM freq can be whatever w/ dividers being used. I'd suggest running your RAM 1:1 w/ the FSB, but many many many others will suggests you run it at crazy high freq's.
3.) Yes.
4.) You can tweak your RAM's timings to get that last .0001% performance increase. Everything should be oc'd in steps, so you can more clearly see when it fails, and what steps are effective at pushing it further.
5.) You really need to read an overclocking guide or 3 (short answer memtest86+ & Prime95 25.x)
6.) See answer to #2. Yes:Yes

You have no need to OC your ram. Run it at 1:1 and theoretically you can reach 4.8GHz (533*9=4797MHz). Ram timings have SUPER SMALL INSIGNIFIGANT performance boost/hinderance to your system in the real world (but you can see the differences in benchmark programs (synthetic)). Is superPI and Prime95 your favorite games/programs? If not, dont worry about RAM.

LOL! actually true... I know some stuff... to sum it up n00b<"me"<expert
Truth is i am an extreme developer, symbian apps, java and carbide tools... I have no real job in hardware other than networks!

My dad jus said I can buy any comp i want with a budget of 3000$ as a result of me winning the RAD faceoff India 2007... So in short "yes" i really dont have a clue as to what i am doing other than wanting to have the best and bestest performing system....

can you suggest some good DDR2 1066 MHz ram which i can shop? corsair is available, I am in India remember, so OCZ n some others not available... What is the word on transcend aXeRam??

Any 1066RAM will do. Doesn't have to be fancy, doesnt have to have tight timings. All it has to do is not have errors at its rated freq (memtest86+ at 1066 for a few hrs, no errors good to go).

I've had to warranty ram from 2 companies (Kingston and OCZ). I cited my memtest86+ errors (test#, # of errors) and kingston gave me the RMA right there, OCZ Asked me to do some tests w/ their direction and then issued the RMA.
memtest errors can occur w/ good ram, just if you have timings too tight or running the ram at too high of a freq it will produce errors. You see no performance gain going from CL5->4. I'd suggest starting out w/ CL5, then if you feel it really necessary, move down to CL4 once you've hit your desired OC w/ the QX9650.

What would he gain from DDR3? IF IF IF he can push is FSB past 533 then all he has to do is loosen up timings more, add a little voltage or set a divider so DDR<FSB.

I'll recommend a PSU: http://www.newegg.com/Product/...x?Item=N82E16817703009

Suppose there is some kinda error while running memtest86+ which indicates a memory error, is it possible to get a warranty replacement citing the same??

Damn, to have problems like that ($3000 to spend on a computer).

You've picked out the top end cpu, why not go all the way and get the ASUS Maximus Extreme motherboard and bump up to DDR3-1800 memory?

Just make sure you also get a solid powersupply for this system, don't cheap out and try to use the "500W" unit included with many cases these days. For this kind of machine, go with a Seasonic, Tagan, Corsair, or maybe OCZ model in the 600W or higher flavor. And use a UPS to prevent power spikes from the wall causing grief.

For PSU, I guess you could go with the PC Power and Cooling 750W Quad.

Nice stuff anyway. I would point you out some deals on newegg, but you are in India... Good luck with your computer, that is a desirable problem. Any DDR2 - 1066 will do, and look for the Tuniq Tower or ThermalRight Ultimate CPU HSF. I don't want to know about the video card(s).

 

[bharatwaja]

Ya thot of that initially... DDR3-1600 and maximus extreme... but doesnt come within $3000 limit... having a $1000 CPU really reduces choices further on... as for the power supply i thot of goin with TP3-650 from antec and a gigabyte 3d Aurora 570 case... others include a 8800GT and g5 Gaming mouse + g15 Keyboard from logitech... seagate 500GB 7200.11....

 

[bharatwaja]

8800gt is jus a temp soln.... waiting for the 9800gtx ... guess another 5 months or so. 8800gt shud do gud till then....

At least your not wasting the money on raptors (unless you edit video's are large pictures). For a top notch system, get more then 1 hdd, bigger the better (500GB is good, 750GB or 1TB is better). 1 hdd for your OS. One for where games are installed. One for the page file (this one can be like 200GB or more). One for filesharing. I have my OS and programs on the same hdd, but you could go a bit more extreem and install your programs to another hdd as well. When I hop on computers w/ just 1 hdd, they are a bit more sluggish.
Seperate those disk I/O's. RAID0 you ask? Crappy real world performance increase (unless you edit video's are large pictures. Its those large sequential reads where it shines).

I never suggested putting games and the OS on the same hdd, but that is what most people do. As for how many hdd's I'm suggesting for your super-rig is:
1.) OS+programs (adobe, browser, java, flash, word processing, etc... ya know.. productive stuff)
2.) Games
3.) File sharing
4.) Pagefile

And you use partitions so for general storage, you just make a partition on the unused portion of the hdds, and put your files there (as you only access that data rarely or at least that data your not worried about disk performance).

 

[bharatwaja]

Technically, how many hard disks are you suggesting? I thought of getting one 200 GB for OS and programs and one 500 GB for all other purposes........

Actually what is the point in having games and OS on same hard drive?
