Hi guys. Thank you for the numbers. I just love good metrics
-And Ben. No harm intended. Its' just that I've been working with statistical analysis quite a bit over the years, and a 10% increase is considered a very substantial increase in most scenarios. I'm glad you were proven right. And I'm glad I got the numbers to help me make my decision.
Ok guys, then I guess it would be smart to go for the faster RAM. I just found an 8 GB DDR3 HyperX Predator 2666 MHz kit for the NOK equivalent of 255 US bucks at my most trusted vendor over here. I wonder if I might just get that.
I originally wanted a 16 GB kit, as I intend to do more than just FSX on the rig. Then again how often do I really need more than 8 Gigs, even when I do picture processing?
As far as price is concerned the only 16 GB 2400 kit available to me over here, with ok timings, is the Corsair Dominator Platinum DDR3 2400MHz 16GB. It retails here for about 450 USD. There are others, of course, but I like the Dominator Platinum series and they are not all that more expensive than the similar kits. If I had found the Dominator Platinum 2666 kit in stock somewhere I would have been really happy.
The Predator kit, at 255 bucks is still not cheap, and here I was just now complaining about the price of 2400 MHz kits. Still it's about exactly the same price tag as the 1600 MHz 16 GB Dominator Platinum kit I was considering earlier.
If I decide to drop the 16 gigs requirement and aim for 8 GB of 2400 MHz I can get a 8 GB 2400 Predator kit for about 100 bucks.
According to this test: "http://www.pureoverclock.com/Review-detail/kingston-hyperx-predator-8gb-kit-2x4gb-ddr3-2666mhz-cl11-dimm/9/" the 2666 kit has it's sweet spot at 2400 too. The price difference would kind of make it sensible to go for the 2400 kit. Still, the price difference isn't all that much when you even it out across the intended life cycle of the rig.
The timings of the 2666 kit running at 2400 is way tighter than you get with the Predator 2400 kit, giving a good boost to throughput too. If I manage to convince myself that every bit matters when it comes to milking enough performance from the rig to feed our favorite CPU- beast on five 22" screens I might just be able to justify the expense. (I think I might be able to do that. )
My current system with a Nehalem i3 3,3 GHz, 16 GB 1333 Mhz RAM and an ASUS Radeon 7770 really doesn't seem to struggle all that much with three screens at a total of 5040X1024 pixels, even with 3rd party planes with REX, ORBX and A2A add ons and pretty high settings overall. Then again for the time being I mostly enjoy flying GA aircraft, not the big complex airliners. However when the time comes and I want to go for bigger planes and the big airport add ons I might need every bit of speed I can squeeze out of my system. The old rig is not going to die btw. It's just going back to it's old life as my dedicated music studio rig.
Having all that FSim equipment in my home studio means I'n hardly have room to play music. Actually, my tiny library/music room/studio space is now so filled up with all the components for my new rig that I really don't have any room to fly either. I can't move the chair back from the desk. So I better get it over with and assemble it soon now.
The list of my new rig components so far is:
Mobo: ASUS P8Z77-V PRO
CPU: i7 3770k
GPU: HIS HIS Radeon HD 7970 GHz X 3GB (for 5 screen Eyefinity).
CPU cooler: Corsair h100.
PSU: Chieftec Nitro BPS-850C
Case: Xigmatek Elyseum
Monitors: Five 22", different brands, HP, Eizo and Benq (for free. :-D )
All of this, except for the CPU, was bought on sale. That has so far saved a total of USD 550 from my budget for the pc components alone, not counting in the huge savings on the monitors. The monitors I found in the electronic recycle dumpster at work. (-And just that was what triggered the new build project).
I guess those savings means I can afford to spend some money on the best RAM I can get my hands on right now. The price difference between the 16 GB 2400 kit and the 8 GB 2666 kit is also a little more than the price for a good 120 GB SSD, and just 40-50 bucks short of the 240 GB Corsair force GT series 3 I just found on sale.
I haven't made up my mind totally yet, but that solution has the following benefits: The kit is in stock and I can get it here in a few days. I can assemble and tune the rig now and just forget about what's inside that box for a while. That is exactly what I'm aiming for. I'd rather spend time flying instead of reading specs and calculating budgets. I get enough of IT project budgeting in my job as an IT Architect and I'm starting to get bored with reading about PC components after literally months of reading forums and obsessing about the "perfect solution".
If I don't do it I will have to spend even more time checking up on what RAM kit that will give me the most bang for the buck, literally, and wait for it to turn up at a vendor here. Sigh. It's not easy being a perfectionist.
-Still, I wish there was a vendor here that carried the 16 GB Predator 2666 kit. I might have considered it. Oh, well... Repeat: I don't need more than 8 gigs, I don't need more than 8 gigs, I don't need....
I wonder what the real world risks of buying two kits of 8 GB instead of one 16 GB are. I know the manufacturers say that they are not able to guarantee that you can OC the RAM as far as you'd be able to with a factory matched kit, but what are the realities. Surely they would be able to run at their designated clock speed no matter what? Do anyone here have any experience with OC-ing two identical RAM kits? Just curiosity of course.
Kind regards
