  1. Can't find the PSU on the Thermaltake websites - strange. Do you have a link to it?
  2. Welcome to OCC mate! Build looks great as far as I can tell. I would probably stick with the HyperX 1.65 v RAM - spending more money on the RAM is one of the worst investment you could make as the performance gains for slightly tighter timings/speeds are usually minimal in real life. Probably spend the extra money on a better CPU cooler as Black64 suggested above
  3. Ok I felt like breaking the self-commenting fiasco lol

  4. Hi mate and welcome to OCC! Apologies for the wall of text in advance but I want to be thorough... Questions: Are you planning on overclocking your CPU? What is your budget for your PSU? Where you looking at buying your system from? An Important Note on PSUs: Do not skimp on paying for a good PSU. The PSU is the most important part of your computer and it is therefore important that you get a solid and reliable one. Cutting costs in this area and buying a bad PSU may cost you the life of your other (expensive) components. PSU Wattage Requirements: I use the following Power Calculator to work out wattages (I have the pro version however - which gives me the amps on each voltage rail). It's not perfect and usually overshoots the power needed in real life but it does give a good estimation as to how much your computer can draw at near MAXIMUM load (which is not very common but does happen). The total number of amps on each rail are more important that total wattage however - especially amps on the +12 volt rail(s) - this is what you should look at when deciding whether a PSU can run a certain system. For your current setup with the GT240, your system will need a maximum power of about 350W with ~23 amps on the +12 volt rail when under full load and while having your CPU overclocked to 4.5 GHz (assuming you ARE planning on overclocking since you are going for the K version of the chip). Since the graphics card will have the biggest impact on your power consumption and since you are looking at a 150 Euro price for a new card, I tried the power values for a GTX560ti and got about 450W draw at maximum load (under the same CPU overclock as before), with about 30 amps on the +12 volt rail. So a 500W PSU will be alright if it has the right number of amps on the +12 rail but it may be pushing it purely based on the number of PCI-e 6+2 pin connectors a 500W PSU usually has (newer graphics cards like the GTX560ti sometimes need 2 of these connectors but many 500W PSUs only come with one connector). In the end I would probably look for a total wattage of 550-650W with a larger total number of amps (>35 A) on the +12 rail(s). This give you a bit of a power overhead for any future upgrades. My Recommendations: The NOX URANO 500W given is not a very good PSU. It's not 80%+ verified (has bad efficiency levels of ~72%) doesn't have active PFC and only has 1 PCI-e connector which will be pretty restrictive if you want to upgrade your graphics card. I would probably stay away from that PSU and personally go for something like a Corsair V2 550TXM or V2 650TX/TXM (Corsair are renowned for making good quality PSUs). Both have 2 PCI-e connectors, Bronze Efficiency rating (about 85% efficiency at most load levels) and the 550W can supply 45 amps on the +12 volt rail while the 650W can provide a maximum of 53-54 amps on the +12 volt rail which is way more than enough for your system.The only downside is that I don't know their prices or your budget The PSUs I mentioned above are just some of a number of good quality PSUs around and you can find more at OCC's Recommended Power Supply List (It's a bit outdated so you might find a few dead links but its still a good guide). I would recommend reading this article to understand more about PSUs and what to look for when buying one. Hope that helped a bit and looking forward to your response!
  5. No worries. Wish you all the best for your finals my friend! 2974 MHz is perfect as bloomfields chips (like the i7 930) require the uncore to be at least 2x the DDR speed - ie: 1487 MHz DDR speed implies >= 2974 MHz uncore The P6X58D-E motherboard manual says that uncore freq. is given by UCLK in the BIOS. I think it might be set to AUTO in the BIOS which is why you can't see its value. But this is getting off topic now...
  6. Go to page 2 of the overclocking guide I gave you above. It explains what QPI and Uncore frequencies are
  7. Umm electron beam on an LCD? I thought only CRT screens used an electron beam to draw the image... Or are you talking about the refresh rate lines you can see if you look at your LCD screen using a video camera?
  8. Yeah I think that memory frequency difference will be negligible to your overall system performance. Btw, in case you didn't know, I found this to be an awesome guide to overclocking bloomfield and gulftown processors (first gen 1366 pin i7's).
  9. What is you RAM speeds for both settings? Have you tested the computer at either setting? Also what is your uncore frequency? Now for your question: From what little computer architecture I have learnt - System RAM is generally slow in comparison to CPU and CPU cache RAM. Usually cache operates at a frequency very close to that of the CPU while system memory operates at a much lower frequency (RAM speeds) meaning that it takes longer to Read/Write to System memory than it does to cache. Fortunately software code is written in such a way that the next instruction or whatever memory information which the CPU needs is close to the instruction which was called previously or close to the data which was called previously. Thus by simply grabbing a large block of data (a bit after and before the current instruction/data) from System RAM and putting it into cache you are able to run software faster (in theory). You still have to access system RAM obviously but not as often thus increasing performance. Given this, we know that increasing the overall CPU frequency will allow you to process things faster and access your cache faster. Having a slightly lower memory speed will increase the time it takes to obtain data from the system memory but because this memory is slow either way, it wont have as much impact on performance since cache is less affected by RAM speeds than it is by CPU frequency. Disclaimer: This is all a very high level view, based on a broad understanding of general computer systems from a course I took at university. I would not be surprised if it is wrong due to differences in how certain CPU's work (maybe cache is more closely connected to the RAM speeds in the i7 930 than I think) but it does sorta help describe what is going on and why I believe it would probably be better to keep in the increased CPU frequency with slower RAM speeds than it is to have faster RAM speeds and lower CPU frequency. Please correct me if I am wrong guys! I would love to learn more about computer systems My 5 cents
  10. That's only for the grand prize (the full system) - anyone can sign up for the other prizes. You should have got an email Premium. Make sure you sent it to the right spot and if so PM Bosco to check if he got it.
  11. MSE All the way - it is similar to how AVG free used to be when they gave everything for free not the half hearted stuff they give free now. Free, uses minimal resources and is pretty effective.
  12. +1 for the Hyper 212 Evo - OCC Review
  13. Despite its many many flaws I gotta say BF3 is the best game this year (dont have Skyrim so I cannot comment on it)
  14. Sorry guys, forgot to mention that we live in Adelaide and are looking to buy local. I'll check out the sites you gave however Stonerboy to see if we can find a good deal - though I doubt the postage will make it any cheaper compared to local prices. I suggested the laptop option to him too but he said his dad wanted a desktop. I will ask him again however if it turns out to be the cheaper option. Thanks for the suggestions! Ill look into them and post back any questions/thoughts when I get a bit more time to check it out.
  15. Hi guys, A friend of mine has asked me to look into getting parts for a new computer he plans on building for his dad. It will be used mainly for surfing the net, writing documents, etc - not stuff that is too CPU or GPU intensive. They have a screen, keyboard and mouse and I am looking at getting Windows 7 Pro for ~$100 using a university student discount (he's a fellow uni student) so all he needs is the box and goodies inside. The following are the shops which we are looking to buy our parts from: Getright Computers, Allneeds Computers, MSY Technology The budget is: $300 AUD - I know a fair amount about higher end components (after being on these forums for a year ) but for lower end stuff I'm very much a noob/rookie which is why I need your help. So I'm looking for a: 1) CPU (hopefully one with on board graphics - so we don't need to buy a card) 2) MOBO 3) RAM (Is 2gb enough or better go 4 gb?) 4) PSU (about 450 - 500W range?) 5) HDD (<= 500 gb will do) 6) L-Cheapo case 7) DVD Recorder Appreciate any help you guys can give!
  16. The 560ti was designed to compete with the 6870 not the 6950. This means that by getting a 6950 you will have slightly higher overall performance compared to the 560ti - not by a huge amount mind you but still by a small margin. Check out OCC's review of the ASUS 560ti for more info. What prices are you looking at for each card?
  17. Generally people buy sound cards for the lower latency they provide when they need to do sound recording, editing, etc For gaming onboard is the bomb.
  18. "If I need to spend 15 hours working on a report, then I want to be miserable from the report itself and not because my hands are cramping from the unusual keyboard design." - valid point.
  19. Sorry but where this thread is going is so worthy haha
  20. Good point! Might be worth waiting for them if they are coming out soon.
  21. Hi mate. Just a few comments. RAM: You will want to get at least 2 sticks of RAM rather than going for a single stick so that you can double your memory bandwidth by running it in Dual Channel mode. So if you still want 4 gigs get 2x2Gb sticks instead - there is a notable difference between single channel and dual channel memory (Read this to find out more). PSU: Max wattage you will be using is about 500 W if you run two 6870's in crossfire at full bore. If you get a single 6950 you'll need only about 400W maximum so I don't see a problem with going down to a 650W PSU (as long as its a good brand) which ever way you go. GPU: Remember you will only get a scaling benefit for games which support crossfire if you get another 6870. If you get a 6950 you will get a performance boost across the whole board (regardless of crossfire support) so following that logic it might be a better idea to go for the single 6950. Some people might disagree though and that's fine. I don't really haven too much experience with dual/triple card set ups so feel free to wait for a second opinion on this. Hope that helps!
